在其定义中的类变量？ [英] Class variable within its definition?

问题描述

这可能是一个愚蠢的问题。我试图做一个文本泥。我需要每个Room类包含其他房间类，人们可以参考时，试图移动他们或从他们获取信息。但是，我不能这样做，因为我显然不能在其定义中声明一个类。那么，我该怎么做呢？这是我的意思，当我说我不能这样做：

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;
};

推荐答案

不可能有 Room 成员变量。

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