What are the best practices for using interfaces in C++?

When using interfaces in C++, it's important to define clear and concise interfaces, use pure virtual functions, and ensure proper documentation.

Can you explain why pure virtual functions are important?

Pure virtual functions allow you to create abstract classes that define a contract for derived classes, ensuring they implement specific methods.

How do I document my interfaces effectively?

You should include comments that describe the purpose of the interface, its methods, and any expected behavior or constraints.

Are there any common pitfalls to avoid?

Yes, avoid creating overly complex interfaces, and ensure that your interfaces are stable and do not change frequently.
