// Check Even or Odd Using Bitwise AND
#include <stdio.h>

int main() {
    int num;

    // Step 1: Prompt the user to enter a number
    printf("Enter an integer: ");

    // Step 2: Read the integer input from the user
    scanf("%d", &num);

    // Step 3: Check if the number is even or odd using the bitwise AND operator
    // If the LSB is 0, num & 1 will be 0 (even)
    // If the LSB is 1, num & 1 will be 1 (odd)
    if ((num & 1) == 0) {
        printf("%d is an even number.\n", num);
    } else {
        printf("%d is an odd number.\n", num);
    }

    return 0;
