In this chapter, we are discussing folding several times; this is an operation that applies a binary function to a range of values to produce a single value. We have seen this when we discussed variadic function templates and will see it again with higher-order functions. It turns out there is a significant number of cases where the expansion of a parameter pack in variadic function templates is basically a folding operation. To simplify writing such variadic function templates C++17 introduced fold expressions that fold an expansion of a parameter pack over a binary operator. In this recipe, we will see how to use fold expressions to simplify writing variadic function templates.

Overview of this book
C++ is one of the most widely used programming languages. It is fast, flexible, and used to solve many programming problems.
This Learning Path gives you an in-depth and hands-on experience of working with C++, using the latest recipes and understanding most recent developments. You will explore C++ programming constructs by learning about language structures, functions, and classes, which will help you identify the execution flow through code. You will also understand the importance of the C++ standard library as well as memory allocation for writing better and faster programs.
Modern C++: Efficient and Scalable Application Development deals with the challenges faced with advanced C++ programming. You will work through advanced topics such as multithreading, networking, concurrency, lambda expressions, and many more recipes.
By the end of this Learning Path, you will have all the skills to become a master C++ programmer.
