What are the best practices for handling exceptions in C++11?

In C++11, it's important to use exceptions for error handling. Best practices include using std::exception as a base class, ensuring exception safety, and avoiding throwing exceptions from destructors.

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 guarantee, strong guarantee, and basic guarantee.

What should I do if I need to throw an exception from a destructor?

It's best to avoid throwing exceptions from destructors. Instead, consider using a flag to indicate an error or log the error without throwing.

Are there any specific exceptions I should avoid throwing?

Yes, avoid throwing exceptions that are not derived from std::exception, as they may not provide useful information about the error.
