[prog] using strings in C++

[Wolf Rising]

This is a project I've been working on for quite a while, the idea was
to create a program that allows the user
to catalog cds. At the moment, I'm only trying to get it to allow the
user to enter 10 cds, and I would like
the option of writing it to a text file (I'm not sure if that part
works yet or not...)

The program compiles and runs but there are at least two things I know
of that aren't working correctly.
First, if you have a entry with more than one word it fouls things up,
for example if you enter just
Beatles, it will prompt you correctly for the next line, enter The
Beatles and it thinks you've
entered two different fields. Also, at the end when it should display
back what the user has entered,
it displays a series of numbers. Any ideas, help, suggestions would be
appreciated. Usual disclaimer,
I'm not a student just trying to learn.

Thanks!
