Question

: Implement the following given scenario in C++ a. Create an inheritance hierarchy by writing the source code, containing base class BankAccount and derived classes SavingsAccount and CheckingAccount that inherit from class BankAccount. b. Implement Polymorphism where required to achieve the polymorphic behavior. c. Multiple constructors be defined for initializing the account of a user. d. The class should provide four member functions. i. Member function Credit should add an amount to the current balance. ii. Member function Debit should withdraw money from the Account and ensure that the debit amount does not exceed the Account's balance. If it does, the balance should be left unchanged and the function should print the message "Debit amount exceeded account balance." iii. Member function getBalance should return the current balance. iv. Define a friend function ‘get_account_info()’ which will allow user to check account details of a particular account holder. e. Derived class SavingsAccount should inherit the functionality of an Account, but also include a data member of type double indicating the yearly interest rate (percentage) assigned to the Account. SavingsAccount's constructor should receive the initial balance, as well as an initial value for the SavingsAccount's interest rate. (Make sure to call the base class constructor appropriately.) SavingsAccount should provide a public member function calculateInterest that returns a double indicating the amount of interest earned by an account. Member function calculateInterest should take one integer argument indicating the number of years gone by, and should determine the interest amount by the formula I = B *(1+ r)t , where I is the interest, B is the initial balance, r is the interest rate, and t is the number of years gone by. [Note: SavingsAccount should inherit member functions credit and debit as is without redefining them.] f. Derived class CheckingAccount should inherit from base class Account and include an additional data member of type double that represents the fee charged per transaction. CheckingAccount's constructor should receive the initial balance, as well as a parameter indicating a fee amount. g. Create 2 object of savings account with different amounts and then overlaod ‘+’ operator to add their current balance and display total balance from the two accounts. h. Use Exception handling in the main/demo class which will validate the withdrawal transaction on a particular class. The creation of objects of the base and derived classes may be kept in the try block to prevent a creation of the base/abstract class object, or assignment of a base class object to a derived class reference.
