Exercise 11.3: Structure
Here is the problem specification:
Write a program that uses a structure to store the following data about a customer account:
- Name
- Address
- City, State, and ZIP
- Telephone Number
- Account Balance
- Date of Last Payment
The program should use an array of at least 10 structures. It should let the user enter data into the array, change the contents of any element, and display all the data stored in the array. The program should have a menu-driven user interface.
Input Validation: When the data for a new account is entered, be sure the user enters data for all the fields. No negative account balances should be entered.
