C++ Fundamentals

By: Brent Arnold

Overview of this book

C++ has come a long way and is now adopted in several contexts. Its key strengths are its software infrastructure and resource-constrained applications, including desktop applications, servers, and performance-critical applications, not to forget its importance in game programming. Despite its strengths in these areas, beginners usually tend to shy away from learning the language because of its steep learning curve. The main mission of this book is to make you familiar and comfortable with C++. You will finish the book not only being able to write your own code, but more importantly, you will be able to read other projects. It is only by being able to read others' code that you will progress from a beginner to an advanced programmer. This book is the first step in that progression.

Variadic Templates
A parameter pack is a template parameter that can accept zero or more template arguments. A parameter pack is declared by appending … to the type of the template parameter. A template that has a parameter pack is called a variadic template, since it is a template that accepts a varying number of parameters. When instantiating a variadic template, any number of arguments can be provided to the parameter pack by separating them with a comma.
