c-program to check weather the year is leap year or not | c-programming questions

 program to check  leap year or not in c-programming.

In this program, user will enter the values and  check weather the year is leap year  or not .

It is not true to say that If a year is divisible by 4 then it is a leap year and it is not divisible by 4 then it is not a leap year. 

 A year is a leap year if and only if :-

 .It  is first divisible by 100 ,then it should  also be  divisible by 400.

. except this , if the year is divisible by is  4 then it is leap year.

lets us write this logic in c-program. To understand this program in c-programming.

 #include<stdio.h>
#include<conio.h>
void main()
{
   int year;
   printf("enter the number\n");
   scanf("%d",&year);
   if(year%100==0){
         if(year%400==0)
                  printf("leap year");
         else
                  printf("not a leap year");
   }
   else{
         if(year%4==0)
                  printf("leap year");
         else
                  printf("not a leap year");
   }
   getch();
}

output: 

                 enter the values of the year a= 200

                     200 is a leap year.
