C++ Features You Might Not Know - Obscure Language Elements and Surprising Behaviors

Explore obscure C++ features in this conference talk from C++ on Sea 2023. Delve into strange syntax, surprising undefined behavior cases, overlooked language facilities, and forgotten standard library functions. Learn about commutative array indexing, complicated declarators, and unexpected operator behaviors. Discover how to leverage these features to write better C++ programs or create intriguingly complex code. Gain insights from Jonathan Müller, a library developer and C++ standardization committee member, as he covers topics including arrays, comma operators, member pointers, floating-point exceptions, declarators, lambdas, and more.
