BufferTracker Destructor Logging

#include <iostream>
using namespace std;

// Write your BufferTracker class here

class BufferTracker{
    private:
    int count;

    public:
    BufferTracker()  noexcept : count(0) {};
    ~BufferTracker()  noexcept {
        cout << "PROCESSED=" << count;
    };

    void addByte(int b) noexcept{
        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;
}
