This chapter acts as a refresher on C++ 11-20, which will be used throughout this book. We'll explain why C++ represents a great opportunity that shouldn't be missed when it comes to writing good quality code that's concise and more portable than ever.
This chapter does not contain all the new features introduced by C++ (11 through 20) – just the ones we will be using for the rest of this book. Specifically, you'll get a refresher (if you already know) or learn (if you are new) about the most essential new C++ skills needed to write modern code. You'll work, hands-on, with lambda expressions, atomics, and move semantics, just to mention a few.
This chapter will cover the following recipes:
- Understanding C++ primitive types
- Lambda expressions
- Automatic type deduction and decltype
- Learning how atomic works
- Learning how nullptr works
- Smart pointers – unique_ptr and shared_ptr
- Learning how semantics works
- Understanding concurrency
- Understanding the filesystem
- The C++ Core Guidelines
- Adding GSL to your makefile
- Understanding concepts
- Using span
- Learning how Ranges work
- Learning how modules work
