Advanced C++

2A. No Ducks Allowed – Types and Deduction

Learning Objectives

By the end of this chapter, you will be able to:

• Implement your own classes that behave like built-in types
• Implement classes that control which functions the compiler creates (Rule of Zero/Rule of Five)
• Develop functions using auto variables, like you always have
• Implement classes and functions by making use of strong typing to write safer code

This chapter will give you a good grounding in the C++ type system and allow you to write your own types that work in that system.

Introduction

C++ is a strongly typed, statically typed language. The compiler uses type information related to the variables that are used and the context in which they are used to detect and prevent ...
