✅ Check Even or Odd Using Bitwise AND in C

#include <stdio.h>

int main() {
    int num;
    printf("Enter a number:\n");
    scanf("%d", &num);

    // Using bitwise AND operator
    if (num & 1)
        printf("%d is Odd\n", num);
    else
        printf("%d is Even\n", num);

    return 0;
}

📘 Explanation:

This C program determines whether a number is even or odd using the bitwise AND operator:

In binary, even numbers end with 0 and odd numbers end with 1.
num & 1 isolates the last bit of the number.
If the result is 1, the number is odd. If it's 0, it's even.

This method is efficient and used in low-level systems and embedded code for performance.

🧾 Sample Output:

Enter a number:
11
11 is Odd

Enter a number:
24
24 is Even
