Exploring C++20

Book excerpt: Discover everything you need to know about C++ in a logical progression of small lessons that you can work through as quickly or as slowly as you need. This book divides C++ up into bite-sized chunks that will help you learn the language one step at a time. Fully updated to include C++20, it assumes no familiarity with C++ or any other C-based language. Exploring C++20 acknowledges that C++ can be a complicated language, so rather than baffle you with complex chapters explaining functions, classes, and statements in isolation you’ll focus on how to achieve results. By learning a little bit of this and a little of that you’ll soon have amassed enough knowledge to be writing non-trivial programs and will have built a solid foundation of experience that puts those previously baffling concepts into context. In this fully-revised second edition of Exploring C++, you’ll learn how to use the standard library early in the book. Next, you’ll work with operators, objects, and data-sources in increasingly realistic situations. Finally, you’ll start putting the pieces together to create sophisticated programs of your own design confident that you’ve built a firm base of experience from which to grow. What You Will Learn Grasp the basics, including compound statements, modules, and more Work with custom types and see how to use them Write useful algorithms, functions, and more Apply your skills to projects that include a fixed-point numbers and body-mass index applications Carry out generic programming and apply it in a practical project Exploit multiple inheritance, traits/policies, overloaded functions, and metaprogramming Who This Book Is For Experienced programmers who may have little or no experience with C++ who want an accelerated learning guide to C++20 so they can hit the ground running.
