Thread: Linking logic: is this even allowed?

The objects 'board' and 'record' are not recognizing each other. I've used #ifndef #endif commands to prevent header redundancy, but that might be part of the problem. Anyway:

main.cpp:

Code:

#include <iostream>
#include "cell.h"
#include "board.h"
...

board.h:

Code:

#ifndef BOARD_H
#define BOARD_H
#include "record.h" 
#include "cell.h"
//'board' object definition that contains a 'record' vector
#endif

record.h:

Code:

#ifndef COORD_H
#define COORD_H
#include "coord.h"
#include "board.h"
//'record' object definition that contains a 'board' pointer.
#endif

How do I make this work?

you could use a base class. Make the pointer a base class pointer that both are derived from.

Thanks

No base class is necessary.

Are perfectly acceptable standard statements in c++
They make sure that a header file isnt included twice in a c++ program.

also base class could be easier because it would automatically create a record(Or any other class ADT) for you when you created an instance of the top class (that inherits from the base)

an example is:

Code:

class Test : public base
{
   public:
      Test () : base ();
};
