/*第2題	闖城堡游戲

2.2.1	課程設計的程序功能簡介：
    闖城堡游戲。城堡中設有一些房間和一些陷阱，玩的時候不小心，就落入陷阱。游戲要求玩家能夠安全離開城堡。

2.2.2	課程設計的任務要求： 
（1）一進入程序，顯示漢化命令提示，以便用戶選擇；
（2）擴充游戲規則，讓玩者按城堡的復雜程度選擇游戲的難易程度；
（3）記錄玩者獲勝次數，失敗次數到文件中，并打印輸出；
（4）將所有的函數與數據封裝到類中，并改寫主程序，使程序簡化。
（5）合做時，擴充游戲規則必須不同。
2.2.3	課程設計說明：
（1）可分三種難易程度：簡單；一般；較難。可以為程序增加了一個選擇難易程度的函數。
（2）由于游戲的難易程度不同，城堡的地圖也不同。
     簡單：玩家只能進入roomone，roomtwoeast，roomthreeeast，roomnorth，parlor。相對而言獲勝的機會就比較大，因此最簡單。是為初級者設計的
     一般：玩家能夠進入的地方要比"簡單"級的多一些。除了"簡單"級能進入的屋子外，還能進入roomwest，backdoor，fireplacre。
     較難：在這一級中城堡的地形會變的很復雜。
     為了實現以上的功能，需在原來的程序的基礎上增加了一些新的控制語句。
（3）游戲結束時，需自動顯示玩家的勝敗情況：一共玩了幾次，其中勝利幾次，失敗幾次。為實現該功能，可設了三個變量sum，win，lost..兩個函數printwin(), printlost()。并且在函數doyouquit()和bravesoul()中分別調用了這兩個函數。
（4）評定難易級別：B級,可合做。
