Write a C program to find whether the given number is odd or even, using Bitwise ' & ' Operator.

Write a C program to input any number and check whether the given number is even or odd using a bitwise operator. How to check whether a number is even or odd using the bitwise operator in C programming. Logic to check even-odd using bitwise operator in C programming.

Logic to check even or odd using bitwise operator

The Least Significant Bit of an odd number is always set (1). To check whether a number is even or odd we need to figure out if LSB is set or not.

We use Bitwise AND & operator to check whether a bit is set or not. Similarly, on performing num & 1 it returns LSB of num. If LSB is 1 then the given number is odd otherwise even.

#include<stdio.h>

intmain()

{

int num;/* Input number from user */

printf("Enter any number: ");

scanf("%d",&num);

if(num &1)

{

printf("%d is odd.", num);

}

else{

printf("%d is even.", num);

}

return 0;

}
