Question
a) Define the class bankAccount to store a bank customer's account number, owner's full name, and balance. Your class should, besides many others, provide the following operations: retrieve the account number, retrieve the owner's full name, retrieve the balance, deposit and withdraw money, and print account information. Add appropriate constructors. b) Every bank offers a checking account. Derive the class checkingAccount from the class bankAccount (designed in part (a). A customer with a checking account do not receives interest, but pays service charges if the balance falls below the minimum balance ($100). Add member variables to store this additional information. In addition to the operations i base class, this class should provide the following minimum balance, set service charges, retrieve service charges, post interest, verify if the balance is less than the minimum balance, etc. Add appropriate constructors. nherited from the operations: set minimum balance, retrieve c) Every bank offers a savings account. Derive the class savingsAccount from the class bankAccount (designed in part (a)). A customer with a savings account typically receives interest. In addition to the operations inherited from the base class, this class should provide the following operations: set interest rate, retrieve interest rate, post interest, etc. Add appropriate constructors d) Write a program to test your classes. Do not hardcode inputs in your program; prompt the user for options.Explanation / Answer
