Question
Introduction Create an inheritance hierarchy that a bank might use to represent customers' bank accounts. All customers can deposit ("credit") into their accounts and withdraw ("debit") from their accounts. More specific types of accounts also exist. Savings accounts, for instance, earn interest on the money they hold. Checking accounts, on the other hand, can charge a fee per transaction. Create an inheritance hierarchy containing base class Account and derived classes SavingsAccount and CheckingAccount that inherit from Account. Deliverables » A driver program (driver.cpp) . An implementation of Account class (account.h, account.cpp) An implementation of SavingsAccount (savingsaccount.h, savingsaccount.cpp) . An implementation of CheckingAccount (checkingaccount.h, checkingaccount.cpp) 1 Account class Implement the base class 1.1 Data Members balance (double) 1.2 Member Functions Constructors Defines default and paramaterized constructors. Confirm balance not below zero. If so, set to zero and output an error message. Destructor Defines destructor. Clean up any allocated memory Accessors double getBalance()Explanation / Answer
