Hi, I''m a student learning C++ and my professor isn''t much help, her view is
if you dont get it I ain''t helping you....

We are supposed to do a basic program as a logon system. I got as far as I
could and came up with some errors I could not understand.

Any Help would be appreciated.

修复它以进行编译。我没有检查甚至没有运行代码。

Just fixed it to compile. I did not check or even run the code.

我想知道，（当我处理它时）我遇到了什么问题？
