Check if K-th Bit is Set

Code

#include <stdio.h>

int isKthBitSet(int n, int k) {
    // Check if the k-th bit is set
    if (n & (1 << k)) {
        // Bit is set
        return 1;
    } else {
        // Bit is not set
        return 0;
    }
}

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