C Program to check the number is a leap year or not?

C Program to check the number is a leap year or not?

Problem: 

Write a C program to check if the number is a leap year or not.

Solution:

Logic for a number is leap year or not:

C code to check leap year Using simple if-else

#include <stdio.h>
int main()
{
  int year;
 
  printf("Enter a year to check if it is a leap year\n");
  scanf("%d", &year);
 
  if ( year%400 == 0)
    printf("%d is a leap year.\n", year);
  else if ( year%100 == 0)
    printf("%d is not a leap year.\n", year);
  else if ( year%4 == 0 )
    printf("%d is a leap year.\n", year);
  else
    printf("%d is not a leap year.\n", year);  
 
  return 0;
}

C Code to check leap year More accurate with advance nesting if-else

#include <stdio.h>
int main()
{
    int year;

    printf("Enter a year: ");
    scanf("%d",&year);

    if(year%4 == 0)
    {
        if( year%100 == 0)
        {
            // year is divisible by 400, hence the year is a leap year
            if ( year%400 == 0)
                printf("%d is a leap year.", year);
            else
                printf("%d is not a leap year.", year);
        }
        else
            printf("%d is a leap year.", year );
    }
    else
        printf("%d is not a leap year.", year);
    
    return 0;
}

Demonstration How to check if the number is leap year or not : C code implementation:

[Demonstrating the advance one]

1. Come to logic: We know that a leap year is divisible by 4 and if that is divisible by 100, then it will also divisible by 400.
2. And now check the c code and hopefully you can check the code now.
