Agenda: C++ - Overview Of New Language Features (Around C++20)¶

The audience consists of professional programmers who are not new to C++. As such, rather than reinforcing each topic through exercises, it is more important to discuss matters and to develop a common knowledge and a common sense.

Throughout the training, the presentation style will be live-coding-by-trainer, only falling back to a traditional frontal presentation style where applicable.
