Question

I have written the body of the function in the header file and so do not have a source file. when I tried running my project in visual studio .. I got an

error: Cannot open source file: No such file or directory.

How do I make visual studio understand that the definitions of the function are within the header itself?

Answer 1

You need to create a dummy source.cpp file just containing #include “source.h”

edit – I just tried this – Visual studio will let you do.

test.cpp

#include "test.h"

where test.h

#include "stdio.h"
int main()
{
   printf("hello world");
   return 0;
}

Interesting – but pointless !
