Re: [Dev-C++] Foward declaration

[Shaddow <sh...@ti...>]

I didn't see the original question so I may be answering something that 
hasn't actually been asked.  If so, just ignore what I have to say.

While it's true that you'd get yourself into all kinds of trouble trying 
to have A be a data member of B and B a data member of A, it is entirely 
possible (and actually at times necessary) to have B* be a data member 
of A and A* be a data member of B.  You see this kind of a situation 
frequently in frameworks.

class B;

class A
{
  B* b;
};

class B
{
  A* a;
};
