Moving to C++17 [2017 Class Archive]

“Moving to C++17: The New Language and Library Features” is a one-day training course with programming examples taught by Nicolai Josuttis. It is offered at the Meydenbauer Conference Center from 9AM to 5PM on Sunday, September 24th, 2017 (immediately prior to the conference). Lunch is included.

Course Description

C++17 is the next evolution in modern C++ programming. Although it is not as big a step as C++11, it contains a large number of small and valuable language and library features, which will change the way we program in C++. This one-day tutorial presents all the new language and library features in C++17. We’ll cover the motivation and context of each new feature with examples and background information. We’ll focus on how these features impact day-to-day programming and how to benefit from them in practice.


Students are expected to have a basic knowledge of C++ including C++11.

Students are not required to bring any laptop. We will go through exercises together with the laptop of the presenter.
