It is one reading of the quote, not the author's own explanation. Destructors for virtual bases run in reverse order of a depth‑first left‑to‑right traversal of the inheritance graph. **In simple terms:** Virtual base destructors run opposite to their appearance order. Key Takeaway Understand and respect the order when designing class hierarchies. Themes C++ inheritance resource management Mood technical analytical Type educational reference When to use this quote - Implementing polymorphic libraries - debugging destructor crashes - ensuring proper resource release Key Concepts Object‑oriented design deterministic cleanup Questions to Reflect On - How does this order affect resource deallocation? - When might you need to override this behavior?
