C Program to Check Whether a given Year is a Leap Year

This is a C program to find whether a given year is leap year or not.

This program takes a year as input and finds whether a year is leap year or not.

1. Take a year as input.
2. Check whether a given year is divisible by 400.
3. Check whether a given year is divisible by 100.
4. Check whether a given year is divisible by 4.
5. If the condition at step 2 and 4 becomes true, then the year is a leap year.
6. If the condition at step 3 becomes true, then the year is not a leap year.

Here is source code of the C program to check a given year is leap year. The C program is successfully compiled and run on a Linux system. The program output is also shown below.

1. Take a year as input and store it in the variable year.
2. Using if,else statements to,
a) Check whether a given year is divisible by 400.
b) Check whether a given year is divisible by 100.
c) Check whether a given year is divisible by 4.
3. If the condition at step 2.a becomes true, then print the ouput as “It is a leap year”.
4. If the condition at step 2.b becomes true, then print the ouput as “It is not a leap year”.
5. If the condition at step 2.c becomes true, then print the ouput as “It is a leap year”.
6. If neither of the condition becomes true, then the year is not a leap year and print the same.
