BufferTracker Destructor Logging

#include <iostream>
using namespace std;

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