Check if K-th Bit is Set

Code

#include <stdio.h>

int isKthBitSet(int n, int k) {
    /*
    00->0
    01->0
    10->0
    11->1
    AND logic will keep other bits same and check if kth bit is set or not
    */
    return (n & (1 << k)) ? 1 : 0;
}

int main() {
    int n, k;
    scanf("%d %d", &n, &k);
    printf("%d", isKthBitSet(n, k));
    return 0;
}
