Question

TIC PEO. Design a generic class to hold the following information about a bank account! Balance Number of deposits this month Number of withdrawals Annual interest rate Monthly service charges The class should have the following member functions: Constructor: Accepts arguments for the balance and annual interest rate. deposit: A virtual function that accepts an argument for the amount of the deposit. The function should add the argument to the account balance. It should also increment the variable holding the number of deposits. withdraw: A virtual function that accepts an argument for the amount of the withdrawal. The function should subtract the argument from the balance. It should also increment the variable holding the number of withdrawals. calcInt: A virtual function that updates the balance by calculating the monthly interest earned by the account, and adding this interest to the balance. This is performed by the following formulas: Monthly Interest Rate = (Annual Interest Rate / 12) Monthly Interest = Balance Monthly Interest Rate Balance = Balance + Monthly Interest monthlyProc: A virtual function that subtracts the monthly service charges from the balance, calls the calcInt function, and then sets the variables tha hold the number of withdrawals, number of deposits, and monthl service charges to zero. Next, design a savings account class, derived from the generic account class. The sa ings account class should have the following additional member: status (to represent an active or inactive account

the programing language is C++
