What this book covers
Chapter 1, Learning Modern Core Language Features, teaches you about modern core language features, including type inference, uniform initialization, scoped enumerations, range-based for loops, structured bindings, class template argument deduction, and others.
Chapter 2, Working with Numbers and Strings, discusses how to convert between numbers and strings, generate pseudo-random numbers, work with regular expressions and various types of string, as well as how to format text using the C++20 text formatting library.
Chapter 3, Exploring Functions, dives into defaulted and deleted functions, variadic templates, lambda expressions, and higher-order functions.
Chapter 4, Preprocessing and Compilation, takes a look at various aspects of compilation, from how to perform conditional compilation, to compile-time assertions, code generation, and hinting the compiler with attributes.
Chapter 5, Standard Library Containers, Algorithms, and Iterators, introduces you to several standard containers, many algorithms, and teaches you how to write your own random-access iterator.
Chapter 6, General-Purpose Utilities, dives into the chrono library, including the C++20 calendars and time zones support; the any, optional, variant, and span types; and type traits.
Chapter 7, Working with Files and Streams, explains how to read and write data to/from streams, use I/O manipulators to control streams, and explores the filesystem library.
Chapter 8, Leveraging Threading and Concurrency, teaches you how to work with threads, mutexes, locks, condition variables, promises, futures, atomic types, as well as the C++20 latches, barriers, and semaphores.
Chapter 9, Robustness and Performance, focuses on exceptions, constant correctness, type casts, smart pointers, and move semantics.
Chapter 10, Implementing Patterns and Idioms, covers various useful patterns and idioms, such as the pimpl idiom, the non-virtual interface idiom, and the curiously recurring template pattern.
Chapter 11, Exploring Testing Frameworks, gives you a kickstart with three of the most widely used testing frameworks, Boost.Test, Google Test, and Catch2.
Chapter 12, C++20 Core Features, introduces you to the most important new additions to the C++20 standard—modules, concepts, coroutines, and ranges.
