SO funktioniert es schon einmal nicht:
C
#ifndef __A_H__
#define __A_H__
#include "B.h"
class A{
public:
int x;
B* b;
};
#endifC
#ifndef __B_H__
#define __B_H__
#include "A.h"
class B{
public:
int x;
A* a;
};
#endifC
#include "A.h"
#include "B.h"
int main(){
A* a = new A();
B* b = new B();
a->b = b;
a->x = 1;
b->a = a;
b->x = 2;
cout << a->x << " " << a->b->x << " " << b->x << " " << b->a->x << endl;
return 0;
}
