BufferTracker Destructor Logging

#include <iostream>
using namespace std;

// Write your BufferTracker class here
class BufferTracker {
private:
    int count;
public:
    BufferTracker() {
        count = 0;
    }
    void addByte(int b) {
        count++;
    }
    ~BufferTracker() {
        cout << "PROCESSED=" << 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;
}
