C++ Fundamentals

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.

Working with const or r-value References
A temporary object cannot be passed as an argument for a reference parameter. To accept temporary parameters, we need to use const references or r-value references. The r-value references are references that are identified by two ampersands, &&, and can only refer to temporary values. This video explains this in further detail.
