What are the best practices for inheritance in C++?

Some best practices for inheritance in C++ include using public inheritance for 'is-a' relationships, avoiding multiple inheritance when possible, and favoring composition over inheritance.

Can you explain why composition is preferred over inheritance?

Composition is often preferred because it promotes code reusability and flexibility. It allows you to change behavior at runtime and avoids the complexities and pitfalls of deep inheritance hierarchies.

What are the risks of using multiple inheritance?

Multiple inheritance can lead to ambiguity and complexity, such as the diamond problem, where a derived class inherits from two classes that have a common base class.

How can I implement polymorphism with inheritance?

You can implement polymorphism by using virtual functions in a base class. Derived classes can override these functions to provide specific implementations.
