In this example, I’ll show you How to check Leap Year or Not in C++.

Check Leap Year or Not in C++

To check whether the input year is a leap year or not a leap year in C++ Programming, you have to ask to the user to enter the year and start checking for the leap year. To check that the year is a leap year or not, following these rules:

  • If year is divided by 4 but not by 100, then it is a leap year.
  • If year is divided by both 100 and 400, then it is a leap year.
  • If year is divided by 400, then it is a leap year.
  • And in all other cases, it is not a leap year.

All years which are perfectly divisible by 4 are leap years except for century years (years ending with 00) which is leap year only it is perfectly divisible by 400.




For example: 2012, 2004, 1968 etc are leap year but, 1971, 2006 etc are not leap year. Similarly, 1200, 1600, 2000, 2400 are leap years but, 1700, 1800, 1900 etc are not.

In this program below, user is asked to enter a year and this program checks whether the year entered by user is leap year or not.

C++ Programming Code to Check Leap Year or Not

Following C++ program ask to the user to enter the year to check whether it is a leap year or not, then display it on the screen:

When the above C++ program is compile and executed, it will produce the following result. Above C++ Programming Example Output (for leap year):
