Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {



    // Write your code here


    int count = 0;
    while (n > 0) {
        if (n % 2 == 1) 
            count++;
        n = n / 2;      // Remove last bit
    }
    return count;

}

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