After the long period without updates to C++ until 2011, the language has been continuously improved with new standards. This brings valuable new features to C++ which are interesting. Participants will learn how to use new language features such as constexpr to optimize code size or performance.

We start with new language elements like auto, override and the uniform initialization. With this knowledge, we continue to look into innovations such as constexpr. Of course, Lambdas are discussed as well. They are one of the long-missing elements.

To the delight of all enthusiastic template users, we look at the innovation in C++11: variadic templates.

We also treat move semantics and analyze when it will bring us a profit. Here we talk about what should be considered in their use and in which situations the feature is disabled by the compiler.

Finally, we look at a few selected innovations in the STL. Very interesting for many C++ programmers, here are the smart pointers. But also containers like std::tuple or std::vector are explained.

After the seminar, participants will have a clear understanding of what the new standards bring to them. You can consciously select features from the new language standards for a project and use it safely.

Seats and format

The class is limited to 15 attendees. A minimum of 6 attendees are required.

This is a live virtual training which uses zoom.us as conference software.

Sale end

Ticket sales end 1 week before the event. In the event that at this point the minimum number of attendees has not been reached this class is canceled and all purchased tickets will be refunded.
