Check if K-th Bit is Set

Code

#include <stdio.h>
#include<math.h>
int isKthBitSet(int n, int k) {
    int k1= (n& ((int)pow(2,k)));
    if(k1){
        return 1;
    }
    else{
        return 0;
    }
}

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