c program to check odd or even

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;

}

C program to check odd or even using bit wise operator

#include<stdio.h>
 
main()
{
   int n;
 
   printf("Enter an integer\n");
   scanf("%d",&n);
 
   if ( n & 1 == 1 )
      printf("Odd\n");
   else
      printf("Even\n");
 
   return 0;
}



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;
}




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;
}
