Check if K-th Bit is Set

Code

#include <stdio.h>

int isKthBitSet(int n, int k) {
    // Write your code here
    unsigned int un=(unsigned int)n;
     unsigned char bin[8];
     int i=0;
    while(k>=i)
    {
        bin[i]=un%2;
        un=un/2;
        i++;
    }
    int num=bin[i-1];
    return num ;
}

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