Check if K-th Bit is Set

0Code

#include <stdio.h>

int isKthBitSet(int n, int k) {
    // Write your code here
    return (n & (1<<k))!=0;
    
}

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

Solving Approach

n=8 and k=3
(00001000 & (1<<k))!=0

00001000  (n)
00001000  (1<<k)
----------------------
00001000
(8)!=0
it is true so bit 3 is set
