C++23 is the brand new release of C++ and is currently implemented by major compilers.

C++23 is huge. It will change the way we program more than C++11 did. As usual, not everything is self-explanatory, combining new features gives even more power, and there are hidden traps. So, the key question is what this means in practice.

This training presents all major language and library features of C++23. It covers the motivation and context of each new feature with examples and background information. The focus is on how these features impact day-to-day programming, what it means to combine them, and how to benefit from C++23 in practice.

As a well-known expert of C++, author of several books and an active member of the C++ standardization committee, Nicolai Josuttis will provide this training with a lot of background information. You will understand the new language features and libraries and the benefit of modern C++ to understand and be prepared for a switch to C++17 in commercial software systems.
