将窗口调节和选择菜单封装成类
这是我目前为止觉得自己写的最好的一段c++了，虽然还是挺烂的吧。

为什么为什么为什么少于150字》》凸
算上代码这都多少字了？？
好吧我其实注意到了两个问题
第一个，传参如果和private成员重名了会是一件很麻烦的事情，所以我的private成全统统改名Lvalue
第二个，尽量让一个类完成一个功能，我一开始把两个合在一起写，乱的个我啊
第三个，Console Function其实没有那么难，一些数据类型都是正常向数据类型的封装（huangemingzi——）用的时候直接查msdn就行
但是要注意一下，很多自动转换的数据类型（比如LPSTR-》char*）在其他严格的编译器下是过不去的，所以稍稍谨慎一下
我到现在才知道COORD的x和y都是short
翻滚屏幕刷新闪屏严重的话有这么几个办法
第一个，把cout换成printf
第二个，把清屏换成FillConsoleOutputCharactor
写过的函数最好具有普适性
比如我写的clear_line（）
从一开始我就没打算把现在的位置传参，而是直接读
就是因为我想让这个函数在哪里都能用而不是限定在这个地方
好了，够150了吗？
