Error Handling in C++ - As Easy as "Use Exceptions"?

Explore error handling techniques in C++ through this comprehensive conference talk from NDC Techtown 2022. Delve into the three most common approaches for managing exceptional circumstances during program execution, examining their impact on program architecture, API design, and coding style. Discover whether functions should return error codes, utilize optional arguments via pointers, employ special result-like types, or throw exceptions. Gain insights into fundamental concepts and best practices suitable for developers of all experience levels. Learn about exception safety, adding context to errors, and the characteristics of various error handling methods. Examine the special case of std::optional, naive implementations, functional programming styles, and pattern matching in C++. Investigate pre-conditions, such as non-null pointers, and explore good practices for effective error handling in C++ programming.
