C++ Program development:
Creates a SavingsAccount class
Uses a static data member,
annualInterestRate, to store the annual interest rate for each of the savers
Ensures each member of the class contains a private data member, savingsBalance, indicating the amount the saver currently has on deposit
Develops a member function, calculateMonthlyInterest, to calculate the monthly interest by multiplying the savingsBalance by annualInterestRate divided by 12; this interest should then be added to savingsBalance
Develops a static member function, modifyInterestRate, that sets the static annualInterestRate to a new value
Instantiates two different objects of class SavingsAccount, Firstsaver and Secondsaver, with balances of $1000.00 and $2000.00, respectively; set the annualInterestRate to 2 percent
Calculates the monthly interest and prints the new balances for each of the savers
Sets the annualInterestRate to 3 percent, calculates the next month's interest, and prints the new balances for each of the savers
Include the proper header and make sure you properly comment your program using proper coding conventions.
