Count Set Bits in an Integer

Code

#include <stdio.h>

int countSetBits(unsigned int n) {
    // Write your code here
    int count  = 0;
    for (int i = 0 ; i < 32 ; i++ )
    {
        if (n & (1<<i) )
        {
            count++;
        }

    }
    return count;
}

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