Modern C++ Design Patterns

Design patterns have proven themselves invaluable over several decades and thus knowledge about them is essential to design robust, decoupled systems. Modern C++, however, has profoundly changed the way we use C++, how we think about design and implement solutions. This also affects how we implement design patterns.

Software Design

This training class explores modern C++ design and the modern forms of classic design patterns. It provides guidelines, idioms and best practices for sustainable and maintainable design, which enables programmers to create professional, high-quality code. Amongst others it will answer the following questions:

  • How does good C++ design with a minimum of dependencies look like?
  • What are the most important rules for robust, maintainable, and sustainable design?
  • What are the most common pitfalls in C++ software design?
  • Why does classical C++ design based on inheritance hierarchies fail so often?
  • How are the classic design patterns implemented in modern C++?
  • What are alternatives to the classic design patterns?

After this course, participants will ...
... have a detailed understanding of the essential design principles;
... understand the benefits of separation of concerns;
... be able to design code with minimum dependencies;
... have an impression of the modern alternatives of classic design patterns;
... have gained knowledge about modern design techniques;
... understand how std::function, std::any, and ranges work;
... favor composition over inheritance;
... avoid the usual pitfalls in the context of inheritance;
... know about the importance of value semantics;
... comprehend the advantages of non-intrusive design.

Participants are required to have at least two to three years of C++ experience. The course expects that all participants are familiar with the syntax of the language and have used inheritance and templates before.

Computer Setup
For the hands-on programming tasks, you are expected to use your own machine. Any operating system (Windows, Linux, MacOS, ...), any IDE/editor (MS Visual Studio, CLion, vi, emacs, ...) and any compiler capable of at least C++14 (GCC, Clang, MSVC, ...) can be used
