What are the best practices for handling exceptions in C++?

Some best practices include using exceptions for error handling, avoiding exceptions in destructors, and ensuring exception safety.

Can you explain what exception safety means?

Exception safety refers to the guarantees that a function provides about its state if an exception is thrown. There are three levels: no-throw, strong, and basic.

What should I do if I catch an exception?

When catching an exception, you should log the error, clean up resources, and possibly rethrow the exception if it cannot be handled.

Are there any specific exceptions I should avoid?

Yes, avoid using exceptions for control flow and prefer standard exceptions like std::runtime_error for user-defined errors.
