An example of an AI chatbot conversation about C++ polymorphism best practices.
What are the best practices for using polymorphism in C++?
Some best practices include using virtual destructors, avoiding unnecessary virtual functions, and favoring composition over inheritance.
Can you explain why virtual destructors are important?
Virtual destructors ensure that the derived class's destructor is called when an object is deleted through a base class pointer, preventing resource leaks.
What about the trade-offs of using polymorphism?
Polymorphism can increase flexibility and code reuse, but it may also introduce overhead and complexity, so it should be used judiciously.
Are there any specific design patterns that utilize polymorphism?
Yes, design patterns like Strategy, Factory, and Observer heavily rely on polymorphism to achieve their goals.
