Question
A)Define the class bankAccount to store a bank customer's account number and balance .Suppose that account number is of type int m and balance is of type double . Your class should at least , provide the account number m retrive the balance , deposit and withdraw money , and print account information. Add appropriate constructors.
B) Every bank offers a checking account . Drive the class checkingAccount from the class bankAccount( design in part (a).This class inherits member to store the account number and the balance from the base class. A customer with a checking account typically receives interest , maintains a minimum balance , and pays service charges if the balance falls below the minimum balance . Add member variables to store this additional information . In addition to the opreation inherited from the base class , this class should provide the following opreation : set interest rate, retrieve interest ratem, set minimum balance, retrieve minimum balance, set service charges, retrieve service charges, post interest, verify if the balance is less than the minimum balance , write a check , withdraw(override the method of the base class), and print account information. Add appropriate constructors.
c. Every bank offers a savings account .Derive the class savingsAccount from the class bankAccount(designed in part (a)).This class inherits members to store the account number and the balance from the base class.A customer with a savings account typically receives interest, makes deposits, and withdraws money.In addition to the operations inherited from the base class, this class should provide the foolowing operations:set interest rate, retrieve interest rate, post interest, withdraw (override the method of the base class), and print account information. Add appropriate constructors.
Write a program to test your classes designed in parts (b) and (c).By C++.
