The program uses an if conditional statement. If the condition of a leap year is met, the output of the year is a leap year, otherwise the condition is not established.
Attachment: the conditions for judging leap years. Ordinary leap year: Gregorian calendar year is a multiple of 4 and not a multiple of 100. Century leap year: The Gregorian calendar year is a whole hundred, and it must be a multiple of 400 to be a century leap year.
