30. Count Set Bits in an Integer

#include <stdio.h>

int countSetBits(unsigned int n) {
    int result = 0;
    for(int bitcount = 0; bitcount < 32; bitcount++)
    {
        if(n & (1 << bitcount)){
            result++;
        }
    }
    return result;
}

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