Can't access function from header file

Question

//head.h//
extern int sum(int,int);

//head.cpp//

#include \"head.h\"
#include \"stdafx.h\"
int sum(int x, int y)
{
return (x+y);
}


        

Answer 1

You need to place the inclusion of head.h after stdafx.h. When precompiled headers are enabled the compiler will ignore the contents of all includes that occur prior to (in this case) the inclusion of stdafx.h .

Answer 2

Either remove stdafx.h from the project, and turn of precompiled headers.. or try moving head.h to be included after stdafx.h instead of before.
