(Savings Account Class) Create a Savings Account class. Use a static data member annuallnterestRate to store the annual interest rate for each of the savers. Each member of the class contains a private data member savings Balance indicating the amount the saver currently has on deposit. Provide member function calculate MonthlyInterest that calculates the monthly interest by multiplying the balance by annuallnterestRate divided by 12; this interest should be added to savings Balance. Provide a static member function modifyInterestRate that sets the static annuallnterestRate to a new value. Write a driver program to test class Savings Account. Instantiate two different objects of class SavingsAccount, saver1 and saver2, with balances of $2000.00 and $3000.00, respectively. Set the annuallnterestRate to 3 percent. Then calculate the monthly interest and print the new balances for each of the savers. Then set the annuallnterestRate to 4 percent, calculate the next month's interest and print the new balances for each of the savers. (Savings Account Class) Create a SavingsAccount class.
