Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {
    int sum =0;
    // Write your code here
    while(n){
    sum += n & 1; 
     n = n >> 1;
    }
    
    return sum;
}

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