More about this course

Our C++20 training course is designed to update developer with the new C++ features.

Many modern C++ features are designed to simplify code or improve safety and performance. The use of templates is a common way to write general purpose code and C++ 20 adds yet more features to simplify this type of code.

New Standard Library features are introduced which take advantage of these new C++ features. Other Standard Library features are overviewed which reduce dependence on operating system. These features include support for threading and synchronisation.

C++ has for a long period supported Object Oriented, Generic and Functional style programming, but now also provides support for fluent style programming.

The latest C++20 features can change the way code is written and can improve the structure of code.
