Apply the latest editions of the C++ standard to the implementation of design patterns. As well as covering traditional design patterns, this book fleshes out new design patterns and approaches that will be useful to modern C++ developers. Author Dmitri Nesteruk presents concepts as a fun investigation of how problems can be solved in different ways, along the way using varying degrees of technical sophistication and explaining different sorts of trade-offs.

Design Patterns in Modern C++20, Second Edition also provides a technology demo for modern C++, showcasing how some of its latest features (e.g., coroutines, modules and more) make difficult problems a lot easier to solve. The examples in this book are all suitable for putting into production, with only a few simplifications made in order to aid readability.

You will:

• Use creational patterns such as builder, factories, prototype and singleton
• Implement structural patternssuch as adapter, bridge, decorator, facade and more
• Work with the behavioral patterns such as chain of responsibility, command, iterator, mediator and more
• Apply functional design patterns such as the Maybe Monad
