BufferTracker Destructor Logging

#include <iostream>
using namespace std;

// Write your BufferTracker class here
class BufferTracker{
    int count;
    public:
    BufferTracker() : count(0){}
    ~BufferTracker(){
        printf("PROCESSED=%d",count);
    }
    void addByte(int b){
        count++;
    }
};
int main() {
    int n;
    cin >> n;

    {
        BufferTracker tracker;

        for (int i = 0; i < n; i++) {
            int x;
            cin >> x;
            tracker.addByte(x);
        }
    } // Destructor must print the processed count

    return 0;
}
