代码修改了下，如果你坚持用getchar()你自己修改下。

谢谢，我看看

嗯，代码就是修改得更好的问题。但是现在问题是好像我的VC++程序出问题了
#include <windows.h>这个头文件报错，网上去查也没有什么有用的解释，就是说路径有问题，然后具体怎么办也没有...呐，大神，请教！！！十万火急啊，学校实验室开始裁员了，我刚到大学...不想被糜烂的生活腐蚀~~~垂死的挣扎...

试试下一个windows.h源文件到指定的文件。
用windows系统还没碰到过这个问题

我找了一下...我的\Microsoft Visual Studio\VC98\Include\里面没有WINDOWS.h的文件...我重下一次，谢谢你
