Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {
    // Write your code here

    int result =0;
    while(n != 0)
    {
       int result1 = n & 1;
       result +=result1;
       n = n>>1;

    }
    return result;
}

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