program to find leap year code example

Example 1: leap year c program

#include <stdio.h>
int main() {
   int year;
   printf("Enter a year: ");
   scanf("%d", &year);

   // leap year if perfectly visible by 400
   if (year % 400 == 0) {
      printf("%d is a leap year.", year);
   }
   // not a leap year if visible by 100
   // but not divisible by 400
   else if (year % 100 == 0) {
      printf("%d is not a leap year.", year);
   }
   // leap year if not divisible by 100
   // but divisible by 4
   else if (year % 4 == 0) {
      printf("%d is a leap year.", year);
   }
   // all other years are not leap year
   else {
      printf("%d is not a leap year.", year);
   }

   return 0;
}

Example 2: leap year algorithm

def isLeapYear (year):
    if ((year % 4 == 0) and (year % 100 != 0)) or (year % 400 == 0):
		true
    else:
    	false

Example 3: leap year algorithm

if year % 4 == 0:
  if year % 100 == 0:
    if year % 400 == 0:
      print("leap year")
    else:
      print("not a leap year")
  else:
    print("leap year")
else:
  print("not a leap year")
