Thread: *.h file, function definitions.. help

An example of how you potentially could have things set up in a sample project...

File.H

Code:

#ifndef FUNC_H
#define FUNC_H
int func(int);
#endif

File.Cpp

Code:

#include "File.H"

int func(int data)
{
    ...
}

Main.Cpp

Code:

#include "File.H"

int main()
{
    int result, val;
    ...
    result = func(val);
}

Thus this sample project has 2 cpp files and 1 header file. You compile the 2 cpp files into object files and its the linkers job to combine those (typically along with some other library code) into a fully functioning executable file.
