# (Find the number of days in a month) Write a program that prompts the user to
# enter the month and year and displays the number of days in the month. For example,
# if the user entered month 2 and year 2000, the program should display that
# February 2000 has 29 days. If the user entered month 3 and year 2005, the program
# should display that March 2005 has 31 days.
