Thread: Quick Question

when you create functions in different files, it's a good idea to DECLARE the function prototype in a header file, and DEFINE the function in a CPP. Only include header files.

eg:

Code:

main.cpp---
#include "myheader.h"

int main(void)
{
   MyFunc();
   return(0);
}

myheader.h---

#ifndef MYHEADER_H
#define MYHEADER_H

int MyFunc(void);

#endif // MYHEADER_H

myheader.cpp---

#include "myheader.h"
#include <iostream>
using namespace std;

int MyFunc(void)
{
   cout << "MyFunc\n";
   return(1);
}

doing this will prevent you from having problems with things being defined multiple times. The only functions that you should define a body for in header files are inline functions.

hope this helps
