What is ListP.h? Frankly I am confused as to why you don't use the std::list. I have no idea what a ListP is.

It appears from reading the program that you have a basic understanding of IOStreams and containers. What's the problem specifically? Nobody is going to just finish the program for you (or they shouldn't) but if you tell us what specifically is giving you trouble perhaps someone could give you a hint.

Please don't post 300 line codes and say,"Fix this please" and we'll give you answers
