A

leap year

is defined as any calendar year which meets the following criteria:

If the year is not divisible by 4, it is a common year

If the year is not divisible by 100, it is a leap year

If the year is not divisible by 400, it is a common year

Otherwise it is a leap year

For your program you will take in three integers from the user:

A four digit year

The day of the month (between 1 and 31)

The month (between 1 and 12, 1 representing January and 12 representing December)

Your program will output whether or not the date entered is a valid calendar date.

Be sure to divide your program into functions which perform each major task.

Hint

: There are 30 days in September, April, June and November. If the year is a leap year, there are

29 days in February. If the year is a common year there are 28 days in February. All other months

have 31 days.
