Count Set Bits in an Integer

Count Set Bits in an Integer

#include <stdio.h>

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

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