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 third 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
  • Discover the latest C++ 20 features, including concepts, modules, and ranges
  • 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.
