BufferTracker Destructor Logging

#include <iostream>
using namespace std;

class BufferTracker{
    private:
        int count = 0;

    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;
}
