What’s new in C++ 11, C++ 14, C++ 17 and C++ 20

Content „What’s new in C++11, C++14, C++17 and C++20“

A C++ training for experienced C++ programmers who want to learn the latest C++11, C++14, C++17 and C++20 extensions with Visual Studio 2022.

C++ has been greatly extended in recent years (C++11, C++14 and C++17). The new standard is called C++ 17 and makes programming with C++ easier, safer, more elegant and more efficient. The extensions include

  • initializer lists (which simplify initializations and check for type safety), lambda expressions (which simplify callback functions and the use of STL algorithms), simplifications in class definition, safer conversions, move semantics (which is faster), etc.
  • new classes of the standard library (STL) such as faster hash containers, smart pointers (which often avoid memory leaks), multithreading classes (for parallel execution of threads), Unicode strings, etc.
  • parallel algorithms of the standard library, which are significantly faster than before C++17 simply by specifying another argument.

The contents (here detailed as pdf) of this course can be adapted to the wishes of the participants.

About this C++ Training

Target audience for this C++ training

Experienced C++ programmers who want to learn the state of the art C++ (C++11, C++14 and C++17).

Requirements: Good knowledge of C++

Teaching style of the C++ course

Lecture with many examples. A balanced combination of theory and practice.

  • At the beginning of a new topic, an overview of applications, basic ideas and syntax is given.
  • The concepts and the syntax are illustrated by using carefully selected and proven examples. Often, best practices“ are presented.
  • The manuscript contains numerous practical exercises.
  • If desired, tasks from the work of the students can also be dealt with. This should be arranged before the start of the training.

Training Materials

Extensive and detailed training materials (approx. 200 pages) – Full text, no PowerPoint slides containing only keywords. Therefore, the course materials can also be used as a reference at work.

Place and time of this C++ training

This seminar is offered as an inhouse seminar (at your site). The implementation as a face-to-face seminar is preferred, but is also possible as an online seminar. Dates by arrangement.

Duration: 5 days


Prof. Richard Kaiser has been conducting seminars for companies for many years, mainly on software development and the programming languages C#, C++ and C. He knows the requirements of practice and addresses them in detail, both in the basic concepts and in the details. His clients include renowned global corporations and small and medium-sized enterprises. He is the author of several books on C++, most recently „C++ mit Visual Studio 2019“. He was a member of the DIN standardization committee Information Technology NI-22 for many years.
