Leap Year Checker using C

Problem Statement

In this program we will code a basic program to check whether an year is a leap year or not.

Code

#include

bool leapyear(int year)

{

if(((year % 4 == 0) && (year % 100!= 0)) || (year%400 == 0))

{

 return true;

}

return false;

}

int main()

{

  int year;

  printf("Enter the Year :");

  scanf("%d",&year);

  if(leapyear(year))

  {

    printf("%d is a Leap Year.",year);

  }

  else

  {

    printf("%d is not a Leap Year.",year);

  }

  return 0;

}

Output

Enter the Year : – 2020

2020 is a Leap Year.

Explanation 

To check whether a year is a leap year or not,we rely on two conditions :
1.Year should be divisible by 4 and not divisible by 100.
2.Year should be divisible by 400.
