Question

This is probably a dumb question. I am trying to make a text-mud. I need each Room class to contain other Room classes that one can refer to when trying to move to them or get information from them. However, I can not do that because I obviously can not declare a class within its definition. So, how do I do this? Here’s what I mean when I state I can not do it:

class Room {
    public:
        Room NorthRoom;
        Room EastRoom;
        Room SouthRoom;
        Room WestRoom;
};

Answer 1

It’s not possible to have a Room member variable. You could use a pointer or reference though.

class Room {
    public:
        Room* NorthRoom;
        Room* EastRoom;
        Room* SouthRoom;
        Room* WestRoom;
};
