RE: [Dev-C++] CROSS REFERENCE WITH OBJECTS

[Daniel G. <sp...@ho...>]

Perhaps you can declare both classes as firends of each other (use the 
friend keyword). You can then declare object A in class B and vice-versa (I 
think).

Re: [Dev-C++] CROSS REFERENCE WITH OBJECTS

[Daniel G. <sp...@ho...>]

So if you use a pointer you do not need to make the other class a friend...? 
yes I see I was wrong. A class just defines a type, and since you are not 
needing your class (A) to use the methods and members of B you don't need to 
use friend.

ah.
