问题描述
大家好。
首先我想道歉，如果之前有问过这个问题，但我找不到答案:(。
我需要知道如何将两个类作为变量彼此相对。我知道我必须有前向引用和变量但有人可以告诉我深层复制构造函数，operator =和dereference函数应该在那个例子中应该是什么样的。有时候我会指点一点点。

Hi every one.
First I want to apologize if that question was asked before but I couldn't find the answer for it :(.
I need to know how can I have two classes as variables in each other. I know I have to have forward reference and the variables to be pointes. But can someone show me how should a deep copy constructor, operator= and dereference function should look like in that instance. Pointers for me a little bit hard sometimes.
