Please write the test program(s) (*/main.cpp), the headerfile(s) (*/program.hpp), and the main C++ program (*/program.cpp) of the following with clear notes: The contents for each:

1) program.hpp (there might be more than one) contains pseudo code and the class definition.

2) program.cpp (there might be more than one) contains the code for the class.

3) main.cpp contains psuedo code for main and tests the class.

Description:

Create an inheritance hierarchy that a bank might use to represent customers bank accounts. All customers at this bank can deposit (i.e., credit) money into their accounts and withdraw it (i.e. debit) money from their accounts. More specific types of accounts also exist. Savings accounts, for instance, can earn interest on the money they hold. Checking accounts, on the other hand, charge a fee per transaction (i.e, credit or debit).

Create an inheritance hierarchy containing base class Account and derived classes Savings_account and Checking_account that inherit from base class 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 balance and uses it to initialize the data member. The constructor should validate the initial balance to ensure that it is greater than or equal to 0. If not, the balance should be set to 0 and the constructor should display an error message, indicating that the initial balance was invalid. 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 Accounts balance. If it does, the balance should be left unchanged and the function should print the message Debit amount exceeded account balance. Member function get_balance should return the current balance.

Derived class Savings_account should inherit the functionality of an Account, but also include a data member of type double indicating the interest (percentage) assigned to the Account. Savings_account constructor should receive the initial balance, as well as an initial value for the Savings_accounts interest rate. Savings_account should provide a public member function calculate_interest that returns a double indicating the amount of interest earned by an account. Member function calculate_interest should determine this amount by multiplying the interest rate by the account balance. [Note: Savings_account should inherit member functions credit and debit as is without redefining them.]

Derived class Checking_account should inherit from base class Account and include an additional data member of type double that represents the fee charged per transaction. Checking_accounts constructor should receive the initial balance, as well as a parameter indicating a fee amount. Class Check_account should redefine member functions credit and debit so that they subtract the fee from the account balance whenever either transaction is performed successfully. Checking_accounts versions of these functions should invoke the base-class Account version to perform the updates to an account balance. Checking_accounts debit function should charge a fee only if money is actually withdrawn (i.e., the debit amount does not exceed the account balance). [Hint: Define Accounts debit function so that it returns a bool indicating whether money was withdrawn. Then use the return to value to determine whether a fee should be charged.]

After defining the classes in this hierarchy, write a program that creates objects of each class and tests their member functions. Add interest to the Savings_account object by first invoking its calculate_interest function, then passing the returned interest amount to the objects credit function.

Using user input is not sufficient to test this routine. You must prove that each of the things asked for are working correctly in your program. The intent is to create the correct classes and prove that they work.

To compile the program use: make

You will need to create makefile.
