Problem
a. Create the logic for a program that calculates the due date for a bill. Prompt the user for the month, day, and year a bill is received. Calculate the day the bill is due to be paid as one month later. Print each date in turn by passing its month, day, and year to a method that displays slashes between the parts of the date-for example, 6/24/2012.
b. Modify the method in so it displays each date using a string for the month-for example, June 24, 2012.
