Checking odd or even

1) C program to check odd or even using modulus operator

#include<stdio.h>

main()

{

   int n;

   printf("Enter an integer\n");

   scanf("%d",&n);

   if ( n%2 == 0 )

      printf("Even\n");

   else

      printf("Odd\n");

   return 0;

}

2) C program to check odd or even without using bitwise or modulus operator

#include<stdio.h>

main()
{
   int n;

   printf("Enter an integer\n");
   scanf("%d",&n);

   if ( (n/2)*2 == n )
      printf("Even\n");
   else
      printf("Odd\n");

   return 0;

}

3)Find odd or even using conditional operator

#include<stdio.h>

 

main()

{

   int n;

 

   printf("Input an integer\n");

   scanf("%d",&n);

 

   n%2 == 0 ? printf("Even\n") : printf("Odd\n");

 

   return 0;

}
