This is a class assignment meant to simulate a bank program. A ten digit account number must be enter, length verified, and then additional information entered and stored into parallel arrays. The program is to run until case 0 is chosen during which time outfiles are opened, updated, and closed.

If you need any clarification, I will try my best to answer.

Thank you so much!
