Check If a Number Is a Power of Two

Code

#include <stdio.h>
#include <stdint.h>

/* 
 * Function checks if the passed number is power of two or not
 */
const char* is_power_of_two(uint32_t n) {
    if (n && !(n & (n - 1))) {
        return "YES";
    }
    return   "NO";
}

int main() {
    uint32_t n;
    scanf("%u", &n);

    const char* result = is_power_of_two(n);
    printf("%s", result);
    return 0;
}
