C program to check leap year using Conditional/Ternary operator

 C , OPERATOR , PROGRAM

Write a C program to enter any year and check whether year is leap year or not using conditional/ternary operator (?:). 
 

Required knowledge:

Basic C programming, Conditional operator, Leap year condition 

Leap year condition:

If the year is EXACTLY DIVISIBLE by 4 and NOT DIVISIBLE by 100 then its LEAP YEAR 
Else if the year is EXACTLY DIVISIBLE 400 then its LEAP YEAR 

Else its a COMMON YEAR 

Program:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

/**  * C program to check leap year using conditional operator  */ #include <stdio.h> int main() {     int year;        /*      * Reads year from user      */     printf("Enter any year: ");     scanf("%d", &year);     (year%4==0 && year%100!=0) ? printf("LEAP YEAR") :         (year%400 ==0 ) ? printf("LEAP YEAR") : printf("COMMON YEAR");     return 0; }

Note: We can also write the same program using conditional operator as:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

/**  * C program to check leap year using conditional operator  */ #include <stdio.h> int main() {     int year;        /*      * Reads year from user      */     printf("Enter any year: ");     scanf("%d", &year);     printf("%s", ((year%4==0 && year%100!=0) ?                     "LEAP YEAR" : (year%400 ==0 ) ?                         "LEAP YEAR" : "COMMON YEAR"));     return 0; }

Output

Enter any year: 2016

LEAP YEAR
