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

In C++11, it's important to use exceptions for error handling. Some 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 when an exception is thrown. There are three levels: no-throw guarantee, strong guarantee, and basic guarantee.

What should I do if I can't avoid throwing exceptions?

If you can't avoid throwing exceptions, ensure that your code is exception-safe by using RAII (Resource Acquisition Is Initialization) and properly managing resources.

Are there any specific exceptions I should avoid throwing?

Yes, avoid throwing exceptions from destructors, and prefer to throw exceptions derived from std::exception to provide meaningful error information.
