Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {
    // Write your code here
    int counter = 0;

    while (n != 0)
    {
        if ((n % 2) == 1)
        {
            counter++;
        }
        n >>= 1;
    };
    return counter;
}

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