Define the
class bankAccount to store a bank customer’s account number and balance.
Suppose that account number is of type int, and balance is of type double. Your
class should, at least, provide the following operations: set the account
number, retrieve the account number, retrieve the balance, deposit and withdraw
money, and print account information. Add appropriate constructors.
- Derive the class checkingAccount from the class bankAccount. This class inherits members to store the account number and the balance from the base class. Add member variables to store minimum balance and service charges amount if the balance falls below the minimum balance as additional information. In addition to the operations inherited from the base class, this class should provide the following member functions to performs: set interest rate, retrieve interest rate, set minimum balance, retrieve minimum balance and set service charges, 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.
- Derive the class savingsAccount from the class
bankAccount. This class inherits members to store the account number and
the balance from the base class. Along with this some additional members
to a savings account that typically receives interest, makes deposits, and
withdraws money. In addition to the operations inherited from the base
class, this class should provide the following additional member functions
to do: set interest rate, retrieve interest rate, post interest, withdraw
(override the method of the base class), and print account information.
Add appropriate constructors.
