Check if K-th Bit is Set

Code

#include <stdio.h>

int isKthBitSet(int n, int k)
{
    int shift = 1;
    int shift_1;
    shift_1 = shift << k;
    int shift_2 = (n & shift_1)>> k;
    if( shift_2 == shift)
    {
        return 1;
    }
    else
    {
        return 0;
    }
}

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