// Check Even or Odd using Bitwise AND Operator
#include <iostream>

int main() {
    int number;

    // Step 1: Prompt the user to enter a number
    std::cout << "Enter an integer: ";
    std::cin >> number;

    // Step 2: Use the bitwise AND operator to check the LSB
    // If (number & 1) is 0, the LSB is 0, meaning it's even.
    // If (number & 1) is 1, the LSB is 1, meaning it's odd.
    if ((number & 1) == 0) {
        std::cout << number << " is an Even number." << std::endl;
    } else {
        std::cout << number << " is an Odd number." << std::endl;
    }

    return 0;
