古堡救美游戏

描述
一个命令行游戏，让玩家在一个有很多楼层和很多房间的古堡中探险，玩家的任
务是找到公主并带她离开古堡。房间有很多种，不同种类的房间有不同的出口，
有的房间里有怪物。如果遇到怪物，游戏就失败了。
游戏启动时，玩家位于古堡一楼的大厅，程序显示大厅的信息：房间的名字、有
几个出口、每个出口的名字（如"east"、"south"、"up")。
    Welcome to the lobby. There are 3 exits as: east, west and up.
    Enter your direction to go:
然后玩家可以输入出口的名字来进入那个出口联接的房间，如
    east
则游戏进入那个房间，程序显示那个房间的信息，如大厅一样。玩家则可以继续
选择下一个房间。
一旦进入有怪物的房间，则显示怪物的信息并结束游戏。
一旦进入有公主的房间，则显示公主的信息，玩家还必须寻找出去的路直到大
厅，然后从大厅寻找出口离开古堡。
所有的显示信息和用户输入都采用英文，以简化程序。

要求
1. 至少三种不同种类的房间；
2. 至少五个房间；
3. 怪物和公主所在的房间是随机的。
一下是我写的代码，但是在编译play_game.cpp的时候出现错误：

望牛人帮忙改下错，不胜感激；
