Header files

Hi,

I've done some searching on this site on header files but haven't got much luck...

I was wondering how exactly header files work...
Say for example, I want to create a simple header file to include with my code, what kind of coding do I need in the .h file...
All i know is the command #include "myheader.h"..

Can someone give me some more information on header files?

a header file can have variables, functions, classes, structs, includes, and stuff like that. for example, here is an sample main file:

Code:

---

#include "myHeader.h"

int main(){
    func();
    cout << i;
    retun 0;
}

---

ok, heres the header:

Code:

---

#include <iostream.h>
void func();
int i;

void func(){
  i = 15;
  return;
}

---

of course you can take out any part of this so you can have:

Code:

---

void func();
int i;

void func(){
  i = 15;
  return;
}

---

but youd have to include iostream.h somewhere.

Ah...ok, ... thanks for the reply :)
