What are the best practices for exception handling in C++14?

What are the best practices for exception handling in C++14?

In C++14, best practices for exception handling include using exceptions for error handling, ensuring exception safety, and using RAII (Resource Acquisition Is Initialization) to manage resources.

Can you explain what RAII means?

RAII is a programming idiom where resources are tied to the lifetime of objects. When an object goes out of scope, its destructor is called, automatically releasing resources.

What should I avoid when handling exceptions?

Avoid using exceptions for control flow, catching exceptions by value, and failing to document which functions may throw exceptions.

How can I ensure my code is exception-safe?

To ensure exception safety, you can use strong exception guarantees, which means that if an exception is thrown, the program state remains unchanged.

Are there any specific C++14 features that help with exception handling?

Yes, C++14 introduced features like std::make_unique and std::shared_ptr, which help manage resources and reduce memory leaks during exceptions.
