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;
}
