I had a question for a C++ programmer. Thought I might find one here :)
I have 2 classes that need to reference each other.
"headerA.h"
class A{
public:
int x;
int y;
B *left;
B *right;
}
"headerB.h"
class B{
public:
int a;
int b;
A *parent;
char foo();
}
Give that top is of type A, in top.left.foo() I need to modify top.right.a
Any ideas? I've tried passing a A* in the constructor for B, but the
compiler doesn't
realize that A is a class when I try to compile, and complains about no
type listed.
I seams to be a circular reference since A needs B and B needs A. This
cannot be that
unusual, and has probably been solved before, I just don't know how.
Right now moy only though is to make parent a void* and the cast it to a
A* in the
implementation of B. That removes all type checking though and I'd
rather not abuse
void pointers like that.
