You are developing a BankAccount structure for Parkville Bank. The structure contains fields for the account number, the account balance, and the annual interest rate earned on the account. Write a main()function in which you create an array of five BankAccount objects. Prompt the user for values for all the fields in the five BankAccounts. Do not allow two or more accounts to have the same account number. After all the objects have been entered:
» Display all the data for all five accounts.
» Display the total balance in all five accounts and the average balance.
» After displaying the statistics, prompt the user for an account number and display the data for the requested account, or display an appropriate message if no such account number exists. Continue to prompt the user for account numbers until an appropriate sentinel value is entered.
