beginner problem with class

iansane (7)
Hi,

I'm writing a simple program with seperate header, implimintation, and main files. I understand the concept of objects and classes. I just think I don't understand the syntax or which files to include can anyone see what is causeing my error? I think it has to do with the includes but I've tried different ways and can't get rid of the error.

Thanks and I hope it's not a problem that I posted all the code. Sorry if it is. Let me know and I won't do it next time.

Get rid of this line:
#include "dayOfWeekImp.cpp"

Thanks Return 0. That was so simple I feel kinda dumb now. So I guess the explanation is that because the functions are being called as part of the class "dayOfWeek" there's no need to include the implementation file in main. It's all really part of the class which is already included with the dayOfWeek.h file? Anyway, thanks for pointing that out. It all works perfectly now.
