Despite having been programming in C++ for about a decade, I've never got my head around 'proper' multi-file projects. My projects have been either completely monolithic or have been linked by #including .cpp files (which I understand is not good practice).
The thing is, every time I try to do it properly I get errors. I have attatched a simple project to demonstrate what I mean (MSVC++ 6.0). The .h file is included and the .cpp file has been added to the project but it STILL won't compile.
Maybe you can help.
