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 deposit. The

function should subtract the argument to the account balance. It should also increment the

variable holding the number of deposits.

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, then sets the variables that hold the number of withdrawals,

number of deposits, and monthly service charges to zero.

Next, design a savings account class, derived from the generic account class. The savings

account class should have the following additional member:

Status $($to represent an active or inactive account$)$

If the balance of a savings account falls below $$25,$ it becomes inactive. $($The status member

could be a flag variable$)$ No more withdrawals may be made until the balance is raised above

$$25,$ at which time the account becomes active again. The savings account class should have

the following member functions:

withdraw: A function that checks to see if the account is inactive before a withdrawal is

made. $($No withdrawal will be allowed if the account is not active.$)$ A withdrawal is then

made by calling the base class version of the function.

deposit: A function that checks to see if the account is inactive before a deposit is made. If

the account is inactive, and the deposit brings the balance above $$25,$ the account becomes

active again. The deposit is then made by calling the base class version of the function.

monthlyProc: Before the base class function is called, this function checks the number of

withdrawals. If the number of withdrawals for the month is more than $4,$ a service charge of

$$1$ for each withdrawal will be added to the base class variable that holds the monthly

service charges. $($Do not forget to check the balance after the service charge is taken. If the

balance falls below $$25,$ the account becomes inactive.$)$

Next, design a checking account class, also derived from the generic account class. It

should have the following member functions.

withdraw: Before the base class function is called, this function will determine if a

withdrawal$($ a check written$)$ will cause the balance to go below $$0.$ If the balance goes

below $$0,$ a service charge of $$15$ will be taken from the account. $($The withdrawal will not

be made.$)$ If there is not enough in the account to pay the service charge, the balance will

become negative, and the customer will owe the negative amount to the bank.

monthlyProc: Before the base class function is called, this function adds the monthly fee of

$$5$ plus $$0\mathrm{.}10$ per withdrawal $($check written$)$ to the base class variable that holds the

monthly service charges.

Write a complete program that demonstrates these classes by asking the user to enter the

amounts of deposits and withdrawals for a savings account and checking account. The

program should display statistics for the month including beginning balance, total amount of

deposits, total amount of withdrawals, service charges, and ending balance.
