Prototype of a prototype?

Okay. I have class B which I want to incorporate previously declared class A into. All well and good. But, how would I put a pointer to a class B into class A, without getting a compiler error?

Forward declare:
class B; // Forward declareclass A {private: B *m_pB;};class B {private: A *m_pA;};Note this only works for pointers/references.
hi,
you can use class forward declaration,
write only above class A:
class B;
class A
{
...
}
and before class B:
class A;
class B
{
...
}
