Overview of this book

Learn how the metaprogramming technique enables you to create data structures and functions that allow computation to happen at compile time. With this book, you'll realize how templates help you avoid writing duplicate code and are key to creating generic libraries, such as the standard library or Boost, that can be used in a multitude of programs. The introductory chapters of this book will give you insights into the fundamentals of templates and metaprogramming. You'll then move on to practice writing complex templates and exploring advanced concepts such as template recursion, template argument deduction, forwarding references, type traits, and conditional compilation. Along the way, you'll learn how to write variadic templates and how to provide requirements to the template arguments with C++20 constraints and concepts. Finally, you'll apply your knowledge of C++ metaprogramming templates to implement various metaprogramming patterns and techniques. By the end of this book, you'll have learned how to write effective templates and implement metaprogramming in your everyday programming journey.

This chapter introduced the concept of templates in the C++ programming language.

We started by learning about the problems for which the solution is the use of templates. We then saw how templates look with simple examples of function templates, class templates, and variable templates. We introduced the basic terminology for templates, which we will discuss more in the forthcoming chapters. Toward the end of the chapter, we saw a brief history of templates in the C++ programming language. We ended the chapter with a discussion on the advantages and disadvantages of using templates. All these topics will lead us to understand the next chapters better.

In the next chapter, we will explore the fundamentals of templates in C++.
