Back to Basics: Design Patterns C++ - Chris Ryan - ACCU 2023
Slides: accu.org/conf-previous/accu2023/
Join me on a tour of some of the more useful C++ Design Patterns that you will likely see and need to know. Knowing how to use Design Patterns will help your code's robustness and will enable others to better read your code and intent.
When designing and writing code you will see similar techniques and patterns repeatedly used throughout different systems and programs. An experienced developer saves these tried and true, well debugged techniques in their personal toolbox for later use.
Others have also noticed these patterns in designs. Some of the more useful techniques have been documented and organized in books like "Design Patterns" by the "Gang of Four" (aka "GoF") and "Code Complete" by Steve McConnell. As coding paradigms have changed new design patterns have evolved.
Other design patterns have worked their way into common use through usefulness. Techniques have been given names for quick reference and as a shorthand in the exchange of ideas. Think of Design Patterns as a mental standard library of building blocks for your designs.

As mathematician I see Design Patterns as tricks language.

Hi, I have started to understand an open source project implemented in c++. It looks like the project is heavily using the design patterns and it seems difficult for me to understand the existing code. I've done object oriented programming in c++ and also know introductory level templates. I wonder what other features of c++ (such as smart pointers, template variadic, lambda etc. ) shall I master so that it becomes easy for me to start using/learning the design patterns.

Learn all the core fundamentals of classes & the polymorphic (virtual) mechanism before trying to learn all the new fancier, bells & whistles. The only thing from your list would be to use std::shared_ptr instead of raw pointers*. If you think you know them already lookup "dunning kruger effect" You can't know all the ins and outs because I still learn new things about C++ all the time and I have been doing it for tity years. Your new building must have a good foundation before you can reach for the sky.

template meta programming, template template parameters, constexpr variables, member initialization of different types like container , stack array heap array, templated objects etc., you can also learn const expressions like, constexpr if basically using these things in combination to achieve "compile time polymorphism"

The link to the slides are not working. Would be helpful if someone can take a look !!

Thank you for your comment. We are aware, and the link will be updated with the slides in the near future.
