Question

3个主要问题：

Visual Studio不会打印空白方块，心形，棍棒，黑桃等符号。
从链接列表中删除节点时，我将其值提供给另一个列表中的另一个节点，但是当我删除它时，它也删除了另一个列表中的节点的值，但是idk为什么。
在打印我的值时，我试图在打印前更改一个值，但是并不能更改所有值。它仅适用于标题。

我试图使我的打印功能接收到一个双星节点定义的功能，但它不是那样的，但是我做错了。我尝试复制并粘贴不同的锹和心脏符号，但它始终会打印一个问号。这是针对Visual Studio 2015 btw。而且我的电脑手功能还没有完成，只是打印电脑手的前三张卡。

删除节点会使分配了值的节点出现问题，为什么？为什么不能在打印功能中更改节点值？
