Count Set Bits in an Integer

Code

#include <stdio.h>

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

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