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 ((1&n) == 1){
           count++;
        }
        n = n>>1;
    }
    return count;

}

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