It is sometimes useful to write functions with a variable number of arguments or classes with a variable number of members. Typical examples include functions such as printf
that take a format and a variable number of arguments, or classes such as tuple
. Before C++11, the former was possible only with the use of variadic macros (that enable writing only type-unsafe functions) and the latter was not possible at all. C++11 introduced variadic templates, which are templates with a variable number of arguments that make it possible to write both type-safe function templates with a variable number of arguments and also class templates with a variable number of members. In this recipe, we will look at writing 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.
