Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {
    // Write your code here
 char count=0;
 loop1:
  if(n>0){
    n&=(n-1);
    count++;
    goto loop1;
  }
 return count;
}

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