Tutorial For Header Files?

Is there a tutorial for header files in cprogramming.com? or any other sites? i need full information on what they are used for, how to use them, and how they work etc.

im confused on them right now.... so can i get fullll info about header files and others that are related to it?

you can make header files for your purposes, I'd use them but its simpler just to use one file, but to have a multi-programmer program use header files to load all the different functions that are used for the program. There are some default header files that came with your compiler, they open just like a txt or cpp file would.

i dont get it..

so u use it to do what?

include a file that u made already??

like if i made a file called "blahblah" and it will be in that program im making. i should add the include code to the other files????


pretty confusing..

can someone put it in noob terms

Basically, if you are going to re-use the same code a lot in different programs, it's best to put it into a header file. Then when you include the file into the program (#include "blahblah.h"), you won't need to re-type all the code. It's sort of a convenience thing. For example:

Code:

---

// This "file" is function.h
// I don't know if you know about functions yet or not, but for the sake of the example...
#include <iostream.h> // To display the message

void Say(char * message)
{
    cout << message;
}
// End of function.h

...

// This "file" is blah.cpp
#include "function.h"

int main()
{
    Say("Hello World!\n");
    return 0;
}
// End of blah.cpp

---

I dunno if that helped at all, but here's hoping :)

yea i understand functions already and also i understand that alreayd..

koo now i know what the headers are used for.... kool :)
