c++ - 不断收到错误: expected unqualified id at end of input- C++

Question

当我尝试运行代码时，总是出现在最后一行，因此我一直收到此错误。我正在尝试制作基于文本的冒险游戏。似乎(当我运行此命令时)这是我唯一的错误。但是，如果有更多人注意到您的帮助，将不胜感激。

所以我的问题是:(1)这到底是什么意思，(2)我如何解决它，以及(3)将来如何避免这种情况？

只是警告:此代码有800多行，因此请尽量采取。

编辑:好的，我已经从以前弄清楚了问题，但是，现在我类中的语句将不会输出。我类(class)中的“cout”语句(例如，fairy()类)以及房间标题和描述都将跳过。我将代码重新排列了一下。
