Question 1(5 Marks) (Polymorphic Banking Program Using Account Hierarchy)
Develop a polymorphic banking program using the Account created in Lab No 2. Create
a vector of Account pointers to SavingAccount and CheckingAccount objects. For each
Account in the vector, allow the user to specify an amount of money to withdraw from
the Account using member function debit and an amount of money to deposit member
function credit. As you process each Account, determine its type. If an Account is a
SavingAccount, calculate the amount of interest owed to the Account using member
function calculateInterest, then add the interest to account balance using member function
credit. After processing an Account, print the updated account balance obtained by
invoking base-class member function getBalance.
