Modern C++ Design Patterns [2021 Class Archive]

Modern C++ Design Patterns is a three-day online training course with programming examples taught by Klaus Iglberger. It is offered online from 09:00 to 15:00 Aurora time (MDT), 11:00 to 17:00 EDT,  17:00 to 23:00 CET, Thursday, October 21st through Saturday, October 23nd, 2021 (before the conference).

Course Description

Design patterns have proven to be useful over several decades and knowledge about them is still very useful to design robust, decoupled systems. Modern C++, however, has profoundly changed the way we use C++, think about design and implement solutions. This training explores modern C++ design and the modern forms of the classic design patterns. It provides guidelines, idioms and best practices for sustainable and maintainable design, which enable 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 realized 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;
  • … be able to design with minimum dependencies;
  • … have an impression on the modern alternatives of classic design patterns;
  • … have gained knowledge about modern design techniques;
  • … understand how std::function, std::any, and ranges work;
  • … avoid the usual pitfalls in the context of inheritance;
  • … know about the importance of value semantics;
  • … comprehend the advantages of non-intrusive design.

Prerequisites

Course participants should have a solid base knowledge of C++ and at least one to two years of experience with the language. Additionally, the course is interesting for you if several of the following statements apply to you:
  • You are not aware of the impact of dependencies on code quality
  • You don’t know the SOLID principles or don’t consider them for your work
  • You believe object-oriented programming is about inheritance relationships
  • You consider moving functionality into classes the preferred design choice
  • You don’t comprehend the arcane rules when the compiler is generating the special member functions for you
  • You don’t know the details of move semantics
  • You want to reevaluate classic design patterns
  • You want to get an impression on modern C++ design patterns
  • You wonder about type erasure and expression templates or their value
