Program Plan: Use the class hierarchy created in Exercise 19.10. Add user interaction part by allowing users to input the amount being credited or debited. Modify the information provisioning functionality by informing about the account balance after each interaction based on the account type. Program Description: We will have three classes Account , SavingsAccount and CheckingAccount with desired attributes and operations. We will re-use the class hierarchy created in Exercise 19.10 and make use of virtual functions for implementing credit and debit operations. Usage of virtual functions and overridden methods in the hierarchy will demonstrate dynamic polymorphism and reduce the code overhead significantly.
