Use a SavingsAccount class. Use a static data member annualInterestRate to store the annual interest rate for each of the savers. Each member of the class contains a private data member savingsBalance indicating the amount the saver currently has on deposit. Provide member function calculateMonthlyInterest that calculates the monthly interest by multiplying the savingsBalance by annualInterestRate divided by 12; this interest should be added to savingsBalance. Provide a static member function modifyInterestRate that sets the static annualInterestRate to a new value.

Using a program to test your class. Your program should prompt the user to enter the savingsBalance for two different accounts. It should ask for the annualInterestRate. It should then compute and print the new balance for both the accounts. A sample run would be:

Please enter the savings balance of account 1: 2000

Please enter the savings balance of account 2: 3000

Please enter the annual interest rate: 3

The interest for account 1 would be $5.00 and the balance after one month would be $2005.00

The interest for account 2 would be $7.50 and the balance after one month would be $3007.50

Would you like to change the interest rate? (Y or N): Y Please enter the annual interest rate: 6

The interest for account 1 would be $10.00 and the balance after one month would be $2010.00

The interest for account 2 would be $15.00 and the balance after one month would be $3015.00

Would you like to change the interest rate? (Y or N): N
