C programming is powerful to find out various things using some powerful codes. Users can make use of it to write a program to check leap year in C. Finding that whether a year is a leap or not can be a bit tricky, but here we are going to write a leap year program in C to help you get at ease.
Generally, we assume that if any year number that we take is evenly divisible by 4 is considered a leap year, you cannot rely on that. There are few conditions for a leap year.
Leap Year:
In case the year number is divisible by 4, or you can say 100 and 400, then we can assume that it is a leap year.
To write a program to check the leap year in c, If the year number is divisible by 4 but not divisible by 100, then we can say that it is a leap year.
Not a Leap Year:
If that year’s number is not divisible by the value of 4, it is not considered a leap year.
If the same year number is divisible by 4 and 100, but it may not be divisible by 400, then we can say that it is not a leap year.
We can write a program to find leap year in C to help you understand better about Leap year and its C program. Here is the example.
Program to find leap year in C
Following is the program for leap year in c.
#include <stdio.h>
int main() {
int year;
printf("Enter year: ");
scanf("%d", &year);
// leap year if divisible by 400
if (year % 400 == 0) {
printf("%d is a leap year.", year);
}
// not a leap year if it is divisible 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 years
else {
printf("%d is not a leap year.", year);
}
return 0;
}
Output 1
Enter year: 1700 1700 is not a leap year.
Output 2
Enter a year: 2016 2016 is a leap year.
Leap Year Algorithm
Algorithm of the program for leap year in C
Start
- Take int variable year
- Assign the value to that variable
- Check if the taken year is divisible by 4 but not 100, then DISPLAY “leap year.”
- Check if that year number is divisible by 400, then DISPLAY “leap year.”
- Else, DISPLAY “not leap year.”

FAQ’s
How do you write a program for a leap year?
Leap Year Program in C can be written as.
- It is divisible by 100. In case it is divisible by 100, it should also be divisible by 400.
- Except for this condition, all of the other years that are divisible by 4 are leap years.
