Do some research on what face shapes are side bangs best suited for, but I think they fit mostly anyone. I have them, they're really cute =D


Although they bothered me at first, b/c they kept going into my eyes haha.
Reply:your links worked for me and i deffinitly think side bangs would look good. i like them on mostly anyone but in your case i think it would be a nice change. i wouldnt go to short at first. your sytlist can always go back and adjust the length when she is finished.

Where can I find info on C++, including info on how to use a compiler? I am a COMPLETE novice, I need BASICS!

I know nothing about anything having to do with computer programming. Online would be most helpful, but even books. Thanks.

Where can I find info on C++, including info on how to use a compiler? I am a COMPLETE novice, I need BASICS!
I'd recommend searching Yahoo or Google for C++ projects or tutorials. As for books there is a book called Learn C++ in 21 days, it goes over different things and gives you a project to do every day for 3 weeks. I really enjoyed it. The links below take you to some stuff I've found helful. I'm pretty sure a manual comes with the compiler download however I'm not on my PC right now so I'm unable to tell. Hope this info helps.

Well that error has to deal with linking, so check your functions and classes and make sure you are passing the correct amount of parameters in the function prototype,definition,and calls.





Also, make sure you have write access to where your tring to complie the program...I had this happen to me once, took me forever to figure out.





Also, I really doubt it, but check your pre-processor directives, make sure you include the nessary ones.

How can I find out if my Mac OS X computer has a C++ compiler already included?

I was told that Macs already come with a C++ compiler included, however, I'm not so sure how and where to look for it. Can anybody tell me how to find it? My Mac is version 10.4.7

How can I find out if my Mac OS X computer has a C++ compiler already included?
Your Mac probably does not come with the compiler installed, though it should come with an XCode installer on the CD/DVD, which will give you a compiler (GCC). In the event your system does already have the (GCC) compiler installed, you can verify such by going to Terminal and typing 'cc', 'gcc' or 'g++'. If any of these binaries already exist, the system should find one somewhere among your path.





Hoping everything works out as it should.

The usa have 50 states. each send 2 senators into senate. doesn´ d.c. have senators or representates?

i live in germany so i m not so familiar with us-pilotics. so if each state send 2 senators into senate, and some representatives into the house of representatives, who are this making the people living in washington d.c.? do they have senators to elect?


and is washington d.c. a state (like illinois), or not? do you have 50 states or 51 (with d.c.) included? or do you have 50 states plus washington d.c., as a "special state"?





thanks

The usa have 50 states. each send 2 senators into senate. doesn´ d.c. have senators or representates?
No Washington D.C. does not get any representatives or senators however the Twenty-third ammendment, which was ratified in 1951, states that;


"The District constituting the seat of Government of the United States shall appoint in such manner as the Congress may direct:


A number of electors of President and Vice President equal to the whole number of Senators and Representatives in Congress to which the District would be entitled if it were a State, but in no event more than the least populous State; they shall be in addition to those appointed by the States, but they shall be considered, for the purposes of the election of President and Vice President, to be electors appointed by a State..."





To sum this up in mordern lingo; the District of Columbia does not get any representatives or senators, but for the purposes of electing a president it gets however many votes in the electoral college as it would if it were a state. But it's number of votes cannot exceed the number any state gets, so even if its population is big enough for six votes, if one of the states only has three, then D.C. can't have more than any of the states so it only get three.


But that's only for electing the President and Vice President.


(By the way I'm pretty sure that the actual amount of electoral votes that D.C. gets is three.)
Reply:50 states, correct. but washington DC is not a state. so no representatives/senators for DC.


note: that is where congress, the president and senators reunite also.
Reply:D.C. is not (nor does it deserve to be) a state. And if you had a good look at the leftist losers who mostly inhabit D.C., you'd have to agree that it's a good think they don't have representation on the national level.

The poster who made the remark about Mayor Barry will be gratified to know that Marion Barry is No longer the Mayor. Mayor Williams was recently replaced by Mayor Fenty. Fenty seems to actually be doing a good job as Mayor. He is a fairly young guy and except for his desire to outlaw the 2nd Amendment of the Constitution, he seems to have his head screwed on right. The Supreme Court overturned the District's anti-gun law, so now the citizens can defend themselves.
Reply:No. DC is not a state so they cannot elect representatives to the government. They can't own guns either. It's almost a foreign country in the USA. Lots and lots of crime too. Most of us stay away from there.
Reply:Fifty states, and the District of Columbia which is not a state. DC has a representative and senators, but they are "shadows" and cannot vote in Congress.
Reply:No, they don't. Washington, D.C. is not a state. The DC stands for District of Columbia. We have only 50 states.
Reply:Washington, DC, is technically a city. The District of Columbia is just a region. While it is commonly given its own contestant in Miss America pageants, it does not have representation in the Senate. It does however, have a non-voting member in the House of Representatives. This person is allowed to sit in on sessions and participate in debates, but has no power to vote in decisions. The Congress of the United States is given the jurisdiction over Washington, DC.





There have been attempts in the past to change the representation of Washington, DC, which include statehood, these, however, have been unsuccessful.

1996 Ford Windstar A/C issues. Cold in the front hot in the back.?

1996 Ford Windstar A/C issues. Cold in the front hot in the back.?
I used to have a 1998 Windstar that blew hot air in the back when I had the a/c on. My husband mentioned it to our mechanic and he said he couldn't check it unless it was doing it at the time and I guess it wasn't. The only thing that worked for me was to turn the rear air on while the motor was off. Then it usually blew the cold air. If I turned the control off and tried to turn it on while the motor was running, it would blow hot. If you can get it to blow cold at all then leave the controls alone and don't change them. The times mine would blow hot, I just had to turn the rear air off and forget about it. It's a pain but things could be worse.
Reply:there could be a number of things going on. you don't want to guess at issues like this, go pay the fee to get a diagnostic done and you can go from there

The system is cycling because you may not be getting enough air through the condenser as the baffle controlling the air to the back is not opening. You need to verify this or have a mechanic check.

If you were to put together a c.d. entitled "The Best of '80's Punk", what songs would you include?

Hard to say; most good punk -- including a lot of the songs mentioned in some of the above answers -- was actually from the mid-to-late 1970s. The best of it -- The Ramones, the Buzzcocks, the Damned, the Sex Pistols, the Clash -=- was already on the way out when the Age Of Reagan began and New Wave started taking over. (More that a little of what was mentioned above is really New Wave, not punk.)





BUT -- I checked, and the Ramones' "Rock and Roll High School" was released in 1980, and "Subterranean Jungle" in 1983, so I'll go with those.

Reply:Hi,


There can be two basic reason.





First I hope you are using Turbo C Compiler





One is that you need to write # include %26lt;whatever the header you want%26gt;


e.g. # include %26lt;stdio.h%26gt;


Check if you wrote # include "stdio.h", as some book says you can write this, but there is some other meaning for this. So prefer the triangular bracket





Secondly


Check this settings...


Go to Options %26gt; Directories.


There you need to give the path of wherever your header files and library files are placed...


preferrable


%26lt;your tc path%26gt;\INCLUDE


%26lt;your c path%26gt;\LIB





eg. C:\TC\INCLUDE


C: \TC\LIB





you can find where your header files are placed by going inside the directory and searching for *.h
Reply:u might have installed u r c software in some drive and moved that to some other drive or a different location than u have installed so change the include directories option or the best way is to install that where ever u want it..........and run u r saved file

I`m a beginer in "c" language.When i try to compile it says :unable to open include file"iostream" and ...

it says undefined symbol cout in function main().plz give me the solution.


I use BCC 5.5

I`m a beginer in "c" language.When i try to compile it says :unable to open include file"iostream" and ...
There is no iostream or cout in the "c" language.


Is your program in C++ instead?


If so, try giving it a different extension, like .cpp instead of .c





If that doesn't fix the problem you just need to change the include directory that BCC 5.5 searches.
Reply:iostream and cout are in the C++ standard library so make sure that you are using a C++ compiler and that your file has a .cpp, .cc, or .cxx extension so the compiler treats it as C++.





Good luck!
Reply:you have an option called window in your turboc editor.In it, select path and check whether that path is leading to your BCC 5.5 directory or not. it is the only problem
Reply:make sure the line where you include the file is correct. For instance, the file should be iostream.h, not just iostream. The compiler has a standard set of directories to look for includes, and I can't imagine one that would not include the normal ones in it's default path, but if you're sure the include statement is correct, then look at the documentation for your compiler, see where it searches, and then see why that file isn't there.
Reply:Either you have typo in the #include %26lt;iostream.h%26gt; line





Or your installation is bad (gotta reinstall there)

I'm doing a basic set of accounts for a small club, do i include our assets in the profit and loss a/c?

Profit and Loss - fixed assets are they considered when producing the profit and loss account. i.e. if the club has made a loss in the year of 5k and the fixed assets amount to 4.5k is that considered a loss of 500. and vice versa in respect of a profit?

I'm doing a basic set of accounts for a small club, do i include our assets in the profit and loss a/c?
Normally the only way you use assets in a P%26amp;L is depreciation and possibly amortization- The Assets show up on the balsnce sheet.
Reply:Listen to the guy with 40 years experience he knows what he is talking about..........
Reply:Very simple!Fixed asset are not considered in p%26amp;l acc.What is concidered in p%26amp;l acc. is the depreciation of an asset value.


If the buz made a loos it is non of the buz of fixed asset ,but the buz itself.All that will go to p%26amp;l acc is the depreciation which will also reflect in your balansheet at end of the financial year.For example,if you decide to charge 5k per year for an asset of 60k with a life span of 12 years.It means that, 5k will be charge to p%26amp;l as depreciation each financial year and same amount post to balansheet to reduce the value of the asset.Which means that the value of the asset in the second year will be 55k, which will continue reducing for the period of 12years.


Hope is answerd? if not, lets share your worries.


Regards.
Reply:Fixed assets don't appear in the P %26amp; L. They would appear in the Balance Sheet.





The P %26amp; L is, crudely, what might be called an "income %26amp; outoings" account.

How do I type a equation that include the symbol Pi ? Example = Fc = 1 / 2*Pi*R*C.?

The symbol for Pi is in the ASCII table number 227. If your using microsoft windows hold down the 'alt' key and type in '227' on the number pad, then release the 'alt' key. This should create the Pi charactor you are looking for. Example: π

How do I type a equation that include the symbol Pi ? Example = Fc = 1 / 2*Pi*R*C.?

What is difference between #include and #define? and also what about inline and macro in c, c++?

#include tells the compiler to compile the specified file along with the source.





#define is used for macros; for example, you could use





#define min( a, b ) ( ( a ) %26gt; ( b ) ? ( b ) : ( a ) )





just like you would a function; however, it won't check your types, and your arguments may have unintended effects. The difference from inline is that the compiler will replace the "calls" to the macro with the actual text before compilation.





It can also be used to define constants, such as





#define e 2.718282f





inline tells the compiler to insert the function body wherever it is called; this eliminates the overhead of the function call. It is better to use inline functions over function like macros whenever possible.

What is difference between #include and #define? and also what about inline and macro in c, c++?
#include includes a file


#define means creating the static value.





ex: #include %26lt;stdio.h%26gt;


here including the header file .





#define venkat printf





we can use this as printf


ex:


venkat("This is venkatesh");
Reply:hi





#include is used to include a header file into a c/c++ program





#define is used to define a constant eg- #define pi 3.14





inline are function defined inside a class

In C language How to write some functions in header file and include it to the main program.?

WIthin c language you have can do functions as define within the header file.





For instance:





#if defined(linux) || defined(__APPLE__)


# if !defined(TRUE)


# define TRUE 1


# endif


# if !defined(FALSE)


# define FALSE 0


# endif


# if !defined(max)


# define max(a,b) (((a) %26gt; (b)) ? (a) : (b))


# endif


# if !defined(min)


# define min(a,b) (((a) %26lt; (b)) ? (a) : (b))


# endif


# if !defined(MB_OK)


# define MB_OK 0


# endif


# if !defined(Sleep)


# define Sleep(x) usleep((x) * 1000)


# endif


#endif /* linux || __APPLE__ */





Or you could do something like this which is a macro.


#define TEST_DEVICE(X) (((X).errorCode) != HD_SUCCESS)





So usually within header files we just include typedefs, defines, and functions.





IF we include functions, then in the main class we implement those functions. Think of it as a interface.





For instance:


index.h


=================================


void hdBeginFrame(int hHD);


void hdEndFrame(int hHD);





index.c


=====================


void hdBeginFrame(int hHD) {


.....


}





So instead of declaring the functions in your .c file at the beginning , you could do them within the header file.





IT acts as a interface in other languages. The reason why we have .h files is simple portability. When developers compile their code or module into dlls or so objects and they want their clients to use them, they can check the .h files to see which functions are included within that dll.





That is how we can do it. :)

void MyFunc();





2)now make a Function.cpp file and write following lines in it

Include function.h in ur main.c file by putting this line at the top

Then goes the main() function

or n=1 below the Sigma sign, 100 above, 1/n1 on the right of the sigma sign


This is my program:


keep in mund C++





#include %26lt;iostream%26gt;


using namespace std;


int main ()


{


int i,fact=1,sum;





for(i=1;i%26lt;=100;i++)


{ fact = fact * i;





sum = 1/fact;





cout%26lt;%26lt;sum;


}





return 0;


}





after i compile link it and execute it i get a message saying


Arithmetic Exception (core dumped)


What is that?


Help please who ever is out there.

I cant' figure whats wrong w/my C++ program!HELP!?
This program has a lot of issues


1stly, you should 1st initialize sum to 0 and then use


sum+= 1/fact (because you want the summation and not each of them individually)





the second problem is, that you should be declaring sum as a double and not an int.


int x=1/2 //implies x=0


double x=1.0/2 //implies x=0.5





this brings me to the 3rd problem.


1/fact will always be zero since 1%26lt;fact and both are ints. you need to write that as 1.0/fact





and to wind it up, one last problem, fact(100) is a really large number. it cant be stored as an integer. I am too lazy to try, but I am pretty sure you cant store it as a long either. you will get overflows of numbers (number turning into a negative number), which will skew your results.





I am appending a similar program. see if it makes sense to you


#include %26lt;iostream%26gt;


using namespace std;


int main ()


{


int i,fact=1;


double sum=0; //sum is now double and initialized to 0





for(i=1;i%26lt;=10;i++) //10 and not 100


{


fact *= i;


sum += 1.0/fact; //adding to sum. also 1.0 and not 1


cout%26lt;%26lt;sum%26lt;%26lt;endl; //appending a newline. this helps bufferring the stream and you catch errors better


}


return 0;


}





All the best
Reply:Make sure fact is not 0 at all... I know


you intialied fact before the i loop to one...


but does it stay above 0 all the time in the loop...





usually a arithmetic expcetion means


you try to divide a 0 or...


the division symbol is not the right one..


since it's integer...


remember you are not getting integer result 1/2 is .50





here is what you can do to see what is the probem


take out the sum=1/fact for now and put a


cout %26lt;%26lt; fact %26lt;%26lt; endl; to see if fact is putting out the right numbers... if not than you know..


if it seems right...


put back the sum=1/fact;


but check to see if you are allowed to use / because you are getting a decimal value and you may have to use..


the var real...
Reply:try unsigned long i,fact=1,sum;


instead of int i,fact=1,sum;

I need help with my c++ compiler...?

i am using dev-c++4 as my compiler and i put this in





// my first program in C++





#include %26lt;iostream%26gt;


using namespace std;





int main ()


{


cout %26lt;%26lt; "Hello World!";


return 0;


}





then i compile it and it says i have no errors. so i push execute and nothing happens. wat am i doing wrong?

I need help with my c++ compiler...?
First, make sure you clicked both compile and build (you can also just click build directly).





Run your program from the command line. If you don’t want to, you can put in a (acceptable for beginners only) kludge by adding cin.get() to the end of main. See Google for the problem of C++ program closing too quickly.





Finally, I want to correct a technical error in your choice of words. But it’s critical you learn to make this distinction. Dev-C++ is what is known as an IDE. It is not a compiler itself. Your compiler is MingW (that’s what Dev-C++ is designed to use). MingW is the windows port of the gcc compiler. Knowing these details will help you with your Googling efforts.
Reply:....


cout %26lt;%26lt; "Hello World!";


cin.get();


....
Reply:Your program did work, it outputs Hello World but it was so fast you couldn't see it. Youre next line after the cout line should be a cin statement. The screen will pause for the cin, and you will see your Hello World. Then when you hit enter, the program will finish executing and exit. Without a line to pause the program (cin), the program executes, displays hello world, finishes executing and closes, fast enough where you didn't think anything happened.
Reply:You're program should compile fine, no errors. Did you start a console project, if so, you should use command line or dos box if on windows to run it.

Can a C programmer help me?

I don't understand this function called "streql" (it tests if 2 strings are equal, and it returns 1 if they are, and 0 if not...)





Here is the code, in C:

int streql (char *str1, char *str2)


{


while ((*str1 == *str2) %26amp;%26amp; (*str1))

printf("Testing abcd si abc %d\n", streql("abcd", "abc"));


}








Can you explain me what is the logic of what is written in the "while", and what is the logic of what is written inside the "return"?

Can a C programmer help me?
Look at the while loop


its condition is to check if the 2 pointers point to equal values.


also it checks if the first pointer is not equal to ZERO which means that the first string has ended. if the condition comes true then advance to the next char for both strings. the return statement checks if both strings had ended. if both ended then they match





Take the following example,


"ABCD", "ABCD"





at first *str1 = 'A' and *str2 = 'A' and *str1 != NULL, so advance


*str1 = 'B' and *str2 = 'B' and *str1 != NULL, advance,


.


.


.


at the end *str1 equals NULL after finishing the 'D' check then the while loop terminates


then the return statement checks if both pointers point to NULL (the two strings finished then it returns true.

Reply:while ((*str1 == *str2) %26amp;%26amp; (*str1))

}


return ((*str1 == NULL) %26amp;%26amp; (*str2 == NULL));





str1 and str2 are pointers. The character pointed to moves one to the right each time you execute str1++ or str2++, respectively. "*str1" means what character the pointer str1 is currently pointing at. So the while statement says, while the character pointed to by str1 is the same as the character pointed to by str2 AND while the character pointed to by str1 is not 0 (meaning is not the null character that terminates string str1), then increment the pointers str1 and str2 to go to the next character.





The return statement means to return true if the thing pointed to by str1 is NULL and the thing pointed to by str2 is NULL.





This is a defective function, as far as I'm concerned. You should exit the while loop as soon as there is a difference found in the two strings or as soon as you get to the end of str1. But at that point *str1 should be 0 and *str2 should be 0 if the strings are equal. str1 and str2 are pointers, but *str1 and *str2 are NOT pointers, they are characters. To compare characters to NULL may work, but it is very bad programming. The return statement should say return (*str1 == 0) %26amp;%26amp; (*str2 == 0).

Plz help with this c++ program?

a. Write a pseudo-code that prompt the user to input number of old items and then receive the sold value for each item, calculate the average value, display the items numbers associated with its values and display also the calculated average value on the screen.





b. write down the C++ code for the previous program.

get sold items,sold value


average=sold value/sold items

C++ Programmers, need help. would you?

I wrote this program and i compiled it successfully, this program runs successfully, but when it retrieves data from user the program get closed. whats the prob?


Here is my program and my compiler is Dev-C++





# include %26lt;iostream%26gt;





using namespace std;


int main ()


{


float grade;


printf ("Please enter your grade : ");


scanf("%d",grade);


if (grade %26gt;10){


printf("You have passed the test...");


}


else


{


printf("You havent passed the test...");


}


cin.get();


cin.ignore();


return 0;


}

C++ Programmers, need help. would you?
There are two problems:





1. In the scanf the %d means the input is an integer, but you declared the variable as a float.





2. Also in the scanf, you need to pass a reference to the variable, not the variable itself.





So change it to scanf("%f",%26amp;grade);





And it will work for you. %f means float, and %26amp;variable means take the address of (pass by reference.)





Alternatively, you can declare grade as an int, and keep the %d.








--------------------------------------...


Yes, you're going to have a problem with bogus inputs.





You could check the return value of the scanf call.





if !(scanf("%f", %26amp;grade) {


printf("Rerun the program and try putting in a number this time");


return 1;


}
Reply:I am guessing the enter keystroke you pressed to send your number input to the program zipped you past the cin.get statement and returned (ended). If that´s not the case, you can always through in some trace statements and a few getchar()´s at the end (or step through with a debugger).
Reply:In DEV-C++ you need to add, before your return 0; this linke





"system("PAUSE");"
Reply:cin.get will read a white space because it doesn't expect to read anything from the input. If you run your program from cmd line it won't close automatically after running it (because the cmd session is still active).


The easy way would be to request the user to type in a key to continue, something like...


printf("Press any key to continue...");


scanf("%c",%26amp;key)..


This will require to store useless data in your program and of course it can be avoided. The alternative would be to "pause" the system until the user decides to end the session manually. Just type


system("PAUSE");


at the end and it will pause the program until the user press a key to exit.
Reply:what is the program trying to do, i am a C++ programmer, you can contact me at srp333@comcast.net for help--------------

if(grade %26gt; 10)


{


printf("Your have passed the test.\n");


system("pause");


}


else


{


printf("You havent passed the text");


system("pause");


}


}
Reply:I think it's because the scanf doesn't take the "return" key after the grade : it is still in the buffer, so cin.get() catches it at once, and your program closes without waiting.


In C, you can address the problem in a nasty way by putting a "fflush(stdin);" just after your scanf. There are prettier ways of doing it, but I just can't remember them right now.


I guess if you know the representation of the return key in your system (\n, \r\n, \r), you can make scanf catch it for you at the end of its first parameter (but your code may have portability issues).

Creating a database with c++?

i got this peace of code from the www.sqlite.org web page, but i don't understanded can you explained to me or let me know a easier way to create, open,execute a database c++


#include %26lt;stdio.h%26gt;

}


printf("\n");


return 0;

sqlite3 *db;


char *zErrMsg = 0;


int rc;





if( argc!=3 ){


fprintf(stderr, "Usage: %s DATABASE SQL-STATEMENT\n", argv[0]);


exit(1);


}


rc = sqlite3_open(argv[1], %26amp;db);


if( rc ){


fprintf(stderr, "Can't open database: %s\n", sqlite3_errmsg(db));

if( rc!=SQLITE_OK ){


fprintf(stderr, "SQL error: %s\n", zErrMsg);


sqlite3_free(zErrMsg);


}


sqlite3_close(db);


return 0;


}

Creating a database with c++?
C++ does not contain database tools by itself.


SQLite is a database and has a library that can be used from C/C++.


In the code you pasted you can see:


Declaring a pointer for the database's variable


sqlite3 *db;


Open the database and initializing the pointer (the database file is the first argument of the command line)


rc = sqlite3_open(argv[1], %26amp;db);


Executing a statement (the second argument of the command line), passing a callback that prints for each field it's value (if it's not null).


rc = sqlite3_exec(db, argv[2], callback, 0, %26amp;zErrMsg);


Closing the database:


sqlite3_close(db);

First, do you have those header files somewhere on your system? Second, you need to add the path to the directory where they are in the Addition Include Files to they're picked up when you build the application. You may need to add some Libraries as well, but you should be able to compile with the directory added to the list.

make sure you have the #include %26lt;WHATEVER%26gt; statements at the beginning. The "whatever" should be replaced with something like "stdio.h" or "math.h" depending on what libraries and include files you need.





Also make sure the include files are in the same directory you are working in.

}











Get's this compile error:

Why doesn't this work in C?
char test[7] makes the variable "test" a "char *".


Therefore use "test_ptr = test".

In 'C 'headerfile this way is cuurect or not Q:#include"stdio.h"?

its #include%26lt;stdio.h%26gt;

In 'C 'headerfile this way is cuurect or not Q:#include"stdio.h"?
Both #include%26lt;stdio.h%26gt; and #include "stdio.h" are correct.


The difference between both is very fine but useful i.e





When you use %26lt;stdio.h%26gt;, the C Preprocessor searches for the file in the standard "Include" directory i.e. for example if you have C in a directory called c:\turboc2\ then there is a directory called "Include" which stores all header files. This is the default location where the file is searched for when you write %26lt;stdio.h%26gt; .This is mostly the requirement of a programmer.





But, when you write "stdio.h" , the file stdio.h is searched in whole directory of c:\turboc2 including all subfolders. This may be the case when you define your own headers and you do not store them inside the Include directory.





Thus either you write %26lt;stdio.h%26gt; or "stdio.h" the file still gets included ( unless the header is not present ), but the difference between them is very fine.





Hope It will help.!!!

when i enter that, the error box on the bottom of dev-c++ says





line 8 message: cout undeclared (first use this function)





line 8 message: endl undeclared (first use this function)





also, if i delete line 8 of that, it works fine, a dos box pops up and says press any key to continue.





if you could please give me a few tips upon what i might be doing wrong,


please tell me!

Can i have some help in c++?
You need to either change line 8 to read:





std::cout %26lt;%26lt; "Hello..." %26lt;%26lt; std::endl;





Or add:





using namespace std;





After the #include lines.





You have to tell the compiler in what namespace to find cout %26amp; endl; the first does it explicitly, the second makes all names in the std namespace available in your program.





Edit to luv l: No, it's not %26lt;iostream.h%26gt;, it's just %26lt;iostream%26gt;. The standard library does not use .h for its headers; the .h versions are deprecated and should no longer be used, as they do not use the std:: namespace.
Reply:You need to specify that your working with the standard c++ namespace.





type in "using namespace std;" before your 'main' function.





alternatively, you could use std::cout %26lt;%26lt;" blah blah"; instead if you preferred, putting the std:: before every cout/ cin / any other standard function.

How do I return a range of values from a function in C++?

Need range +/- start/end values


Couldnt fit it all:





#include %26lt;iostream%26gt;


#include %26lt;cmath%26gt;


#include %26lt;string%26gt;


using namespace std;





int start_year, end_year, out_years;





int i = 0;





string proc_year_s(string incl_start_year_f);


string proc_year_e(string incl_end_year_f);


string c_include_s, c_include_e, incl_year_s, incl_year_e, incl_start_year, incl_end_year;





int main( )


{


while(true){


cout %26lt;%26lt; "Leap-Year Calculator\n" %26lt;%26lt; endl;

C prog multiple files?

These are my files. I'm wondering is this the right way to do it.





/* game.h */





#ifndef GAME_


#define GAME_





extern void game (void);


extern void enemyFunc (void);


extern int enemyPosX;





#endif





/* game.c */





#include "game.h"





int enemyPosX;





void game (void)


{


enemyFunc();


}








/* enemy.c */





#include "game.h"





void enemyFunc (void)


{


enemyPosX -= 4;


}








It works but if i take the





extern int enemyPosX;





out of game.h, it still work?

C prog multiple files?
When you take "extern int enemyPosX;" out of game.h, you should indeed get a compiler error when you try to recompile enemy.c, which it sounds like you were expecting. Is there any chance that you didn't actually recompile enemy.c? If you were to use an object file that was created from the original, it would still be able to link.





I suggest you remove any object files and try to compile again.





If it still compiles clean, then what compiler are you using and what commands are you using to compile?





REGARDING YOUR FOLLOWUP, your general structure is correct. It is good form to create a .h file that contains function declarations for the function that will be shared from the .c file to other .c files. You do not actually have to use extern in front of function declarations, as that is assumed, but you would use extern in front of variables that you declare.





You should really try to keep global variables to an absolute minimum, and pass values between functions instead. This will help avoid introducing weird side-effects that are hard to track down. If you have a lot of variables that you need to pass around, you may want to consider creating one or more struct's so you can pass a single pointer to a struct that contains the related variables.





http://www.cs.cf.ac.uk/Dave/C/node35.htm... has some good ideas to follow for creating large proejcts.





http://publications.gbdirect.co.uk/c_boo... covers these details as well, and from there, follow through to chapter 8 for really gory details to consider.

C, C++ Beginner Help ?

Hi People,





I wrote the below given code in "Turbo C" It's Working But When I paste the same code in Dev C++. It's not working.





I am just frustrated.





WHY IT IS NOT WORKING WITH DEV C++


-----------------------------


#include %26lt;conio.h%26gt;


main()


{


textcolor (BLUE) ;


cprintf ( "YourName" ) ;


}


--------------------------------





Long Answers Are Appreciated.





Thanks In Advance.

C, C++ Beginner Help ?
conio.h is not part of the C++ standard. Also, if you are interested in doing console output, C++ uses cout:





http://xoax.net/comp/cpp/console/Lesson2...
Reply:You don't need a long answer. conio.h is turbo c only. You can't convert this program to DEV C++ because conio.h is not a standard c library.

String manipulation C++?

Hi i am working on a small program where a user enters a string which should be more than 8 characters. Then once they have entered a string, the program should do the following:


1) output the size of the sentence


2) output the 1st 3rd 5th and 7th letter and append it to the end of the inputted sentence.





This is what i have done so far but i am getting errors and i am new to c++:





#include %26lt;iostream%26gt;


#include %26lt;string.h%26gt;


#include %26lt;sstream%26gt;


using namespace std;





int main()


{


int iQuit;


char str[7];


cout%26lt;%26lt; "Enter sentence \n";


getline(cin,str);


cout%26lt;%26lt; "Size of the sentence" %26lt;%26lt; str.length() %26lt;%26lt; endl;


cin %26gt;%26gt; iQuit;


return 0;


}





Can someone help on this and the second part please? i could probably do this in java but i need to do in C++.





I would appreciate it if someone can help me on tell me they have done in such a way?

String manipulation C++?
There are two main kinds of string in C++, the null terminated strings inherited from C and the C++ string object. Using the latter makes your assignment a cinch. Unless you are instructed otherwise you should begin to use string objects and move away from null terminated strings whenever possible.








#include %26lt;iostream%26gt;


#include %26lt;string%26gt;





using namespace std;





int main()


{


string input;





while (input.length() %26lt;= 8)


{


cout%26lt;%26lt; "Enter sentence at least 8 characters in length\n";





getline(cin, input);


}





cout%26lt;%26lt; "Size of the sentence = " %26lt;%26lt; input.length() %26lt;%26lt; endl;





input += input[2];


input += input[4];


input += input[6];





cout %26lt;%26lt; "appended sentence is: " %26lt;%26lt; input %26lt;%26lt; endl;





return(0);


}
Reply:Try this code for starters. Can you spot the changes?





#include %26lt;iostream%26gt;


#include %26lt;string.h%26gt;


#include %26lt;sstream%26gt;


using namespace std;





int main()


{


int iQuit;


string input;


cout%26lt;%26lt; "Enter sentence \n";


getline(cin, input);


cout%26lt;%26lt; "Size of the sentence " %26lt;%26lt; input.length() %26lt;%26lt; endl;


cin %26gt;%26gt; iQuit;


return 0;


}
Reply:You can't say str.length(). You have to use the function strlen(), like this:





cout%26lt;%26lt; "Size of the sentence" %26lt;%26lt; strlen(str) %26lt;%26lt; endl;





To output the 1st, 3rd, 5th and 7th letters you have to access them from the string/character-array. This is done like so: str[0] is the 1st. str[2] is the 3rd letter, etc.





Appending is easy. Just make a new character array that is bigger, copy the inputted string to it (using the strcpy function) and then assign the letters that you want to the new string.

C++: How do you edit a character string in a different function than the one you declared it in?

The following code is C++:








#include "stdafx.h"


#include %26lt;iostream%26gt;


#include %26lt;fstream%26gt;


#include %26lt;string%26gt;


using namespace std;





int rewriteString(char *str)


{


str = "I want to output this!";


cout %26lt;%26lt; str;


return 1;


}





void main()


{


int meaninglessInteger = 0;


char str[] = "Why am I outputting this, instead of what I want to output?";


meaninglessInteger= rewriteString(str);


cout %26lt;%26lt; str;


system("PAUSE");


}





******* ******* ******* ******* ******* ******* ******* ******* *******


The above code doesn't work. I wondered if someone could help me understand what I need to change to accomplish what I'm trying to do.


I hope the code is fairly self-explanitory: I want to declare a character string in main() and then use a function called rewriteString() to change the message contained in that character string.





What's the correct way to do this? Any help is appreciated greatly!

C++: How do you edit a character string in a different function than the one you declared it in?
just my two cents ;)





int rewriteString(char *str)


{


strcpy(str,"output");


cout %26lt;%26lt; str;


return 1;


}
Reply:Okay. There is actually a very simple explanation to your answer. Once i tell you, you'll wonder why you didnt think of this in the first place.





Now, from basic C++ programming, you'd know this simple example:





void foo( int f ) { f = 25; }


void main() { int a = 10; foo(a); cout %26lt;%26lt; a; }





Now what do you think will be the output. Correct, it will be 10.


Why? Because the argument f to function foo was "passed by value" variable 'a' never changes its value. Now... just extending this to character strings.





void foo( char * f ) { f = "please please change"; }


void main() { char * t= "dont want to change"; foo(t); cout %26lt;%26lt; t; }


Now, :) i think by now you'd be saying "aaah, hmm... ". So, the solution. If you havent caught on, i'll tell you (this is Yahoo! Answers after all).. you've got two options


1. Pass parameter by reference ... void foo( char *%26amp; f )


2. Pass a pointer to the argument... void foo( char ** f )





I think you can figure out the rest. Due to the lack of availability of a compiler to check my analysis. I might be mistaken over char *%26amp; f... it might be, char %26amp;* f . But i dont think so. Sorry, but you'll have to check that.





Thanks.
Reply:I'm sorry if this is not what you want but I find it easier to just do this...





#include %26lt;iostream%26gt;


#include %26lt;fstream%26gt;


#include %26lt;string%26gt;


using namespace std;





char *rewriteString(char *str)


{


char * random = "theText";


return random;


}





int main() {


char * str = new char[100];


str = "Why am I outputting this, instead of what I want to output?";


str = rewriteString(str);


cout %26lt;%26lt; str;


system("PAUSE");


return 0;


}

I have no clue why you have the meaninglessInteger variable

Why #include<windows.h> header file is used in c programming language?

A header file contains a set of common directives, function references, calls and definitions that are common to most windows progams. Rather than having to enter those details every time you write a program you have them in a file which gets included.





That way you can write a program quicker as you don't have to add the same stuff into every program. It also means that if you want to change any of the common functions you just change it in one file and that file is included in all others automatically.





Wikipedia has a pretty good page about them at http://en.wikipedia.org/wiki/Header_file

Why #include%26lt;windows.h%26gt; header file is used in c programming language?
%26lt;windows.h%26gt; file is the header file that contains all essential API functions of the WINDOWS operating system


you use this file only if you make programs which uses functions for GUI or other system functions


for making simple programs you dont use this file just


%26lt;stdio.h%26gt; and %26lt;conio.h%26gt; is enough.

How far back does a c.r.b. go back and does it include cautions?

How far back does a c.r.b. go back and does it include cautions?
Standard Disclosures are primarily for posts that involve working with children or vulnerable adults. Standard Disclosures may also be issued for people entering certain professions, such as members of the legal and accountancy professions. Standard





Disclosures contain the following;


details of all convictions, cautions, reprimands and warnings held on the Police National Computer (PNC);





and if the position involves working with children or vulnerable adults and the relevant boxes have been marked on the application form to indicate this:





information from the Protection of Children Act List (PoCA);


Information from the Protection of Vulnerable Adults List (POVA); and


Information held by the DfES under Section 142 of the Education Act 2002 of those considered unsuitable for banned from working with children.





Enhanced Disclosures are for posts involving a far greater degree of contact with children or vulnerable adults. In general, the type of work will involve regularly caring for, supervising, training or being in sole charge of such people. Examples include a Teacher, Scout or Guide leader. Enhanced Disclosures are also issued for certain statutory purposes such as gaming and lottery licences.








Enhanced Disclosures contain the same information as Standard Disclosures but with the addition of local police force information considered relevant by Chief Police Officer(s).
Reply:i think the crb looks back as far as you have a record. it also depends if your haing an enhanced check or not may i ask what it is for
Reply:The Criminal Records Bureau (CRB) acts as a ‘one-stop-shop’ for organisations, checking police records and, in relevant cases, information held by the Department of Health (DH) and the Department for Education and Skills (DfES). There are two levels of CRB check currently available; called Standard and Enhanced Disclosures.


The two CRB checks are available in cases where an employer is entitled to ask exempted questions under the Exceptions Order to the Rehabilitation of Offenders Act (ROA) 1974. This includes any organisation whose staff or volunteers work with children or vulnerable adults. They are issued free to volunteers.


Standard Disclosure


This is primarily available to anyone involved in working with children or vulnerable adults, as well as certain other occupations and entry into professions as specified in the Exceptions Order to the Rehabilitation of Offenders Act (ROA) 1974. Standard Disclosures show current and spent convictions, cautions, reprimands and warnings held on the Police National Computer. If the post involves working with children or vulnerable adults, the following may also be searched:


Protection of Children Act (POCA) List


Protection of Vulnerable Adults (POVA) List


Information that is held under Section 142 of the Education Act 2002 (formerly known as List 99)


Enhanced Disclosure


This is the highest level of check available to anyone involved in regularly caring for, training, supervising or being in sole charge of children or vulnerable adults. It is also available in certain licensing purposes and judicial appointments. Enhanced Disclosures contain the same information as the Standard Disclosure but with the addition of any relevant and proportionate information held by the local police forces.


The CRB recognises that the Standard and Enhanced Disclosure information can be extremely sensitive and personal, therefore it has published a Code of Practice and employers’ guidance for recipients of Disclosures to ensure they are handled fairly and used properly.


A copy of the Standard or Enhanced Disclosure will be sent out to the applicant as well as the Registered Body.
Reply:As I understand, a CRB does not include cautions as cautions are just that - a warning not to do it again! It does not constitute a crime for which you have been punished (or even tried).





That said, if you are working with children, deeper checks are now carried out and you should be aware that such stuff MIGHT be included.

C Programming Experts! HELP!!!??
hello,





can u paraphrase your question? is this for receiving data from a port and saving to a file or are u telling us there is a problem with the file opening part but the send data by com is working?





Anyways, .... i am not so sure with my answer but :


1. fopen("C:\\TEMP\\text.txt", "r") -%26gt; fopen("C:\\TEMP\text.txt", "r")





if this is for saving the data from a port it should be :


1. fopen("C:\\TEMP\\text.txt", "w+")


2. while ((c) != EOF) {


c = fgetc(dp); /* get from port */


fputc( c, fp); /* write to the file */


}


3. also try to add : fflush(fp) just before close :)





I hope u can clear out your question so we can help u better. good luck and merry christmas in advance.
