All data-input and data-display operations (cin and cout) should be done in the function main()

with initial balances of $100 each using the functions defined in the class definitions. The test
program should also assign a unique, five-digit account
number to each account and assign an annual interest rate of 3% for the savings account. The
test program should then display a menu that allows the user to select
which option is to be performed on which account, including the following. Make a deposit and
specify the amount to a selected or an entered account. Make a with
drawal and specify the amount to a selected or an entered account. Return the balance of a
selected or an entered account. For deposit transactions, withdrawal
transactions, and balance inquiries, the updated balance and any fees charged or interest
earned should also be displayed. For the savings account, the number of days
since last transaction should be displayed. Exit the program. Each account operation should
display the account number and the account type.
