Count Set Bits in an Integer

Code

#include <stdio.h>


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

    }
    return count;
}

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