ProblemWrite a short program that takes a year as input from the user, and then determines whether or not that particular year is (or was) a leap year. As a reminder, here is the criteria that dictates whether or not a year is a leap year: If the year is evenly divisible by 4, then the year is a leap year -- unless it is also divisible by 100, in which case it is not. An exception to this is if the year is divisible by 400, then it is still a leap year. Example: |
