Question

Write a program that uses a class or 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 or vector of 10 objects. It should let the users enter data, change the contents of any element and display all the data stored in the array or vector. The program should be modular and menu driven. Validation: When the data for a new account is entered, be sure the user enters data for all the fields. No negative account balance should be entered. Testing: Test your program for all the valid and invalid scnerios.
