Leap year program in C
We will know about leap year program in C here. You may have know that leap year is the year which can be divisible by 400 and 4 but not divisible by 100. We can apply this logic to check that the given year is leap year or not.
We can make a leap year program using if else statement or switch statement. Here in this article we will make several leap year program in using C programming language.
Checking leap year using if else in C
// Leap year program in C
#include <stdio.h>
int main(){
int year;
printf("Enter the year you want to check : ");
scanf("%d", &year);
if (year % 400 == 0){ // checking if it is divisible by 400
printf("\n%d is a leap year.\n", year);
}else if (year % 100 == 0){ // checking if it is divisible by 100
printf("\n%d is not a leap year.\n", year);
}else if (year % 4 == 0){ // checking if it is divisible by 4
printf("\n%d is a leap year.\n", year);
}else{
printf("\n%d is not a leap year.\n", year);
}
return 0;
}Output of the leap year program:
Check leap year using switch statement
#include <stdio.h>
int main(){
int year;
printf("Enter the year you want to check : ");
scanf("%d", &year);
int makeInt = (year % 400 == 0) || (year % 4 == 0) && (year % 100 != 0);
switch(makeInt){
case 1:
printf("Leap year.\n");
break;
default:
printf("Not leap year.\n");
}
return 0;
}See the output
Enter the year you want to check : 2020
Leap year.
Process returned 0 (0x0) execution time : 5.803 s
