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.

Using: MS Visual Studio .Net 2003
Language: C++
Program centers around: Classes
