Check if K-th Bit is Set

Code

#include <stdio.h>

int isKthBitSet(int n, int k) {
    // Write your code here
    if((n>>k)&1) return 1;
    else return 0;
}

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

Solving Approach

I just right shifted the original value i.e. n by k (that is the bit position that's to be checked) and performed AND operation with 1. 
If AND result is 1, then the bit is set, otherwise it is not set.
