Getting up to speed with the latest C++ features. C++ continues to remain relevant despite the advent of many new modern languages. This book dives into the significant features of C++20 ("big four") and C++23, addressing challenges and improving development. You will learn how to write cleaner, more efficient, and safer code. From organizing your projects better to handling complex tasks easily, this guide equips you to take your C++ skills to the next level. We start by discussing basic concepts and learning how to use them in templates. Then, we explore advanced topics like asynchronous programming with coroutines and tools for handling multiple tasks at once. You will discover C++ modules for building modular applications to organize code better. You will learn about ranges for processing data sequences efficiently, including views and adaptors for transforming and filtering data. Further, you will explore new features for containers, cleaner coding practices, and performance optimizations in C++2023. The book outlines new features, with lots of code examples. They can use it as a reference guide, or progress through each how-to recipe to maximize their knowledge. This book empowers C++ programmers, from experienced professionals to those looking to level up their skills, by teaching the latest features for writing cleaner, more efficient, and powerful C++ code.
