Write a C Program to Check Leap Year or Not

Question No. 02

Write a C program to check whether it's a Leap Year or Not.

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

	if ( year % 400 == 0) {
		printf("%d is leap year", year);
	} else if (year % 100 == 0) {
		printf("%d is not a leap year", year);
	} else if (year % 4 == 0) {
		printf("%d is leap year", year);
	} else {
		printf("%d is not a leap year", year);
	}
	return 0;
}

Output: Enter The Year
        2023
        2023 is not a leap year.

Algorithm

Step 1: Start,
Step 2: read "Year" from user input,
Step 3: if (year % 400 ==0)
step3.1: True, Print "Year is a leap year,
step3.2: False, jump to step 4,
Step 4: if (year % 100 == 0),
step 4.1: True, Print "Year Is not a leap year",
step 4.2: False, jump to step 5,
Step 5: if(year % 4 == 0),
step5.1: True, print "Year is a leap year,
step 5.2: "Year Is not a leap year",
Step 6: Stop.
