I'm paying 100 fg to help me figure this problem out.

Is there a way I can use a header file in my main program AND in a header file used by my main program? For example:





However I'm getting a "Redefinition" error, I've read about forward declaration but I'm not sure how to apply it here.

Edit:

I did


But it's saying expected unqualified-id before '.' token. So I think I'm supposed to use :: somewhere, but I'm not sure where/how.
It's also saying the member variables (objects of the Class 1 and 2) inside this Class 3.h have incomplete types

put preprocessor guards in the header

#ifndef HEADERNAME_H
#define HEADERNAME_H

...your code goes here... prototypes, classes, etc.

#endif // HEADERNAME_H


This is pretty standard...should be lots more info if you Google/Bing "header preprocessor guards" or something like that.

Cheers!

I already have that, I didn't mention it because codeblocks automatically puts it in.

I'm having a real wtf moment here... There's also "undefined reference to Class1::Class1" when I put in an EMPTY CONTRUCTOR in class 3... i.e: Class3::Class3() { } Why the hell would I get a reference error when I'm not even using the other classes in this constructor? I think this may be linked in some way

You really need to post more of the code that you have. It's pretty worthless to talk about the errors you're getting without showing us any code.
