Thread: 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?

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
