2.12* (Financial
application: calculating interest) If you know the balance and
the annual percentage interest rate, you can compute the interest on the next
monthly payment using the following formula: interest = balance *
1annualInterestRate / 12002
Write a
program that reads the balance and the annual percentage interest rate and displays
the interest for the next month in two versions: (a) Use dialog boxes to obtain
input and display output; (b) Use console input and output.
