Design and implement a program that can be used to provide users with information about the monthly payment for a car loan. The program should allow a user to enter the amount of the loan and the annual interest rate. The program should validate data entered by the user in a reasonable way and should force the user to reenter until the data is correct. The program should display the monthly payment for a 4 year loan, a 5 year loan and a 6 year loan in an attractively formatted table. The formula for calculating the payment is:

payment = (monthly rate * loan amount) / ( 1- (1 + monthly rate) ^ - number of months).
