Before starting with this tutorial we assume that you are best aware of the following C programming topics:

Operators in C Programming.

Basic Input and Output function in C Programming.
Basic C programming.
String functions in c programming.

Check Leap Year or Not.

As we all know the c programming is a very powerful language. In the c programming language, we have many pre-defined functions for arithmetic operations. but today we will check whether the given number is a leap year or not with the help of the c programming language.

With the help of this program, we can Check Leap Year or Not.

Algorithm:-

1. Declare the variables for the program. 

2. Take the input number from the user.

3. Pass that number to a condition.

4. Calculate the leap year from the given number.

5. Print the output string after checking.

6. End the program.

1. Declare the variables for the program.

2. Take the input number from the user.

3. Pass that number to a condition.

4. Calculate the leap year from the given number.

5. Print the output string after checking.

6. End the program.

Program to Check Leap Year or Not:-

#include <stdio.h>
int main()
{
    //declaring the variable for the program
   int yr;
   //taking input year
   printf("Enter the year to check: ");
   scanf("%d", &yr);

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

   return 0;
}

#include <stdio.h>

int main()

{

//declaring the variable for the program

int yr;

//taking input year

printf("Enter the year to check: ");

scanf("%d", &yr);

// leap year if perfectly divisible by 400

if (year % 400 == 0) {

printf("%d is a leap year.", yr);

}

// not a leap year if divisible by 100

// but not divisible by 400

else if (yr % 100 == 0) {

printf("%d is not a leap year.", yr);

}

// leap year if not divisible by 100

// but divisible by 4

else if (yr % 4 == 0) {

//printing output

printf("%d is a leap year.", yr);

}

// all other years are not leap years

else {

//printing output

printf("%d is not a leap year.", yr);

}

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

yr = it will hold the integer value of number input.

Taking input number from the user.

Calculating and Printing output of the program.
