C++: Area Code Program

ALERT: WE HAVE MOVED TO http://codingmassacre.com/!!

Out of boredom, I recently decided to make a program in C++. What you do is enter a United States Area Code from any of the 50 states (or Washington DC) and it’ll tell you that the area code you entered in belongs to the state of ____, listing the state. It is a simple MS-DOS program.

Here is the source code: [click]

Here is a picture of it:

Feel free to give your thoughts/ideas. Any feedback is welcome.

edit: I need to fix how it still says “Please Enter a Valid Zipcode” once you enter a area code and hit enter – it should say area code, and it shouldn’t appear once you enter one.
