Overview of this book

C++ is a general-purpose programming language designed for efficiency, performance, and flexibility. Design patterns are commonly accepted solutions to well-recognized design problems. In essence, they are a library of reusable components, only for software architecture, and not for a concrete implementation. This book helps you focus on the design patterns that naturally adapt to your needs, and on the patterns that uniquely benefit from the features of C++. Armed with the knowledge of these patterns, you’ll spend less time searching for solutions to common problems and tackle challenges with the solutions developed from experience. You’ll also explore that design patterns are a concise and efficient way to communicate, as patterns are a familiar and recognizable solution to a specific problem and can convey a considerable amount of information with a single line of code. By the end of this book, you’ll have a deep understanding of how to use design patterns to write maintainable, robust, and reusable software.

Chapter 7, SFINAE, Concepts, and Overload Resolution Management

  1. For each function call, it is the set of all functions with the specified name that are accessible from the call location (the accessibility may be affected by the namespaces, nested scopes, and so on).
  2. It is the process of selecting which function in the overload set is going to be called, given the arguments and their types.
  3. For template functions and member functions (and class constructors in C++17), type deduction determines the types of template parameters from the types of the function arguments. For each parameter, it may be possible to deduce the type from several arguments. In this case, the results of this deduction must be the same, otherwise, the type deduction fails. Once the template parameter types are deduced, the concrete types are substituted for the template parameters in all arguments, the return type, and the default arguments. This is a type substitution.
  4. Type substitution, described...
