header file confusion

Hi,

  I want to create two classes, say class A and class B. For each class, I have a header file(A.h and B.h) as well as implementation file(A.cpp and B.cpp).  My class A has a member variable which is of the type class B. Also, in my class B, there is a member variable of type class A. i.e. the class definition looks like this:

class A {
B testMember;
...
};

class B {
A testMember;
...
};

I have "include A.h" in the B.h file and also, I "include B.h" in the A.h file. Initially i got error saying some kind of recursion definition too deep. I realized this error and added #ifdef and #endif to my program to avoid the recursion. But then I got some error saying missing decl-specifiers. I wonder what is the proper way of doing this? I am using MSVC 5.0.

Any help is appreciated!
