(Polymorphic Banking Program Using Account Hierarchy) Develop a polymorphic bank- ing program using the Account hierarchy created in Exercise 12.10. Create a vector of Account pointers to SavingsAccount 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 into the Account using member function credit. As you process each Account, determine its type. If an Account is a SavingsAccount, calculate the amount of interest owed to the Account using member function calculateInterest, then add the interest to the account balance using member function credit. After processing an Account, print the up- dated account balance obtained by invoking base-class member function getBalance. What will be an ideal response?
