Check if K-th Bit is Set

Code

#include <stdio.h>

int isKthBitSet(int n, int k) 
{
    int num = 1;

    num = num << k;

    if( (num & n) )
    {
        return 1;
    }

    else
    {
        return 0;
    }
}

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