Question

Problem Definition Create an inheritance hierarchy containing base class Account and derived class Savings-Account. Base class Account should include one data member of type double to represent the account balance. The class should provide a constructor that receives an initial baiance and uses it to initialize the data member. The class should provide three member functions. Member function credit should add an amount to the current balance. Member function debit should withdraw money from the Account and ensure that the debit amount does not exceed the Account's balance. Member function getBalance should return the current balance Derived class SavingsAccount should inherit the functionality of an Account, but also include a data member of type double indicating the interest rate (percentage) assigned to the Account. SavingsAccount's constructor should receive the initial balance, as well as an initial value for the SavingsAccounts interest rate. SavingsAccount should provide a public member function calculatelnterest that retums a double indicating the amount of interest eamed by an account. Member function calculateinterest should determine this amount by multiplying the interest rate by the account balance. [Note: SavingsAccount should inherit member functions credit and debit as is without redefining them.] Part 1: Class Definition Implement the class definition for class Account and SavingsAccount in the files called Account h and SavingsAccount.h. The class definition should contain only the prototypes of the member functions and double members. Part 2.1: Member-function definition Implement the member-function definition of classes in the files calle Account.cpp and SavingsAccount.cpp. This cpp file contains the actual mplementation of the member functions of the two classes Part 2.2: Test program Write a program that tests your class Account and SavingAcounts. Call your file testAccount.cpp. This program should 1. Instantiate an object of class SavingAccounts and Accounts 2. Add some credit to both objects. 3. Add some credit to both objects 4. Withdraw some amount for both objects. 5. Print the interest for the saving account object. 6. Print the current balance of each account.

Please show it in C++. Thank you!
