Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {
    // Write your code here
    int dem=0;
    while(n > 0)
    {
        if(n%2==1) dem++;
        n/=2;
    }
    return dem;
}

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