The program has three main parts:

i$.$ A base class called BankAccount handles the common features of all bank accounts.

ii$.$ A class for Savings Accounts that calculates interest on the balance.

iii. A class for Checking Accounts that allows for overdrafts $($spending more than the available

balance$),$ but with a fee.

We also have tiered interest rates in the SavingsAccount, meaning the interest rate depends

on how much money you have in the account. The more money you have, the higher the interest

rate you get.
