Incomplete type error

[unclefester]

I have two classes: Test1 and Test2. Test1 has a field of data type Test2, & vice versa. I need some help in avoiding the incomplete type error ("Error: field has incomplete type").

Test1.h

#ifndef _TEST1_
#define _TEST1_

#include "Test2.h"

using namespace std;

class Test1
{   public:
       Test2 test2Obj;       
}

#endif

Test2.h

#ifndef _TEST2_
#define _TEST2_

#include "Test1.h"

using namespace std;

class Test2
{   public:
       Test1 test1Obj;       
}
#endif

}

You can't do that: if you recursively define Test1 and Test2 in terms of each other
a Test1 contains a Test2 which contains a Test1 again which contains a Test2,
ad nauseam. Better think of pointers or references to Test1 and Test2 instead.

kind regards,
