C++ Fundamentals

By: Antonio Mallia, Francesco Zoffoli

Overview of this book

C++ Fundamentals begins by introducing you to the C++ compilation model and syntax. You will then study data types, variable declaration, scope, and control flow statements. With the help of this book, you'll be able to compile fully working C++ code and understand how variables, references, and pointers can be used to manipulate the state of the program. Next, you will explore functions and classes — the features that C++ offers to organize a program — and use them to solve more complex problems. You will also understand common pitfalls and modern best practices, especially the ones that diverge from the C++98 guidelines. As you advance through the chapters, you'll study the advantages of generic programming and write your own templates to make generic algorithms that work with any type. This C++ book will guide you in fully exploiting standard containers and algorithms, understanding how to pick the appropriate one for each problem. By the end of this book, you will not only be able to write efficient code but also be equipped to improve the readability, performance, and maintainability of your programs.

Summary


In this chapter, we saw how inheritance can be used to combine classes in C++. We saw what a base class is and what a derived class is, how to write a class that derives from another, and how to control the visibility modifier. We talked about how to initialize a base class in a derived one by calling the base class constructor.

We then explained polymorphism and the ability of C++ to dynamically bind a pointer or reference of a derived class to a pointer or reference of the base class. We explained what dispatch for functions is, how it works statically by default, and how we can make it dynamic with the use of the virtual keyword. Following that, we explored how to properly write virtual functions and how we can override them, making sure to mark such overrode functions with the override keyword.

Next, we showed how to define interfaces with abstract base classes and how to use pure virtual methods. We also provided guidelines on how to correctly define interfaces.

Lastly, we delved...
