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.

C++ Fundamentals


Inheritance allows the combination of one or more classes. Let's look at an example of inheritance:

class Vehicle {
    TankLevel getTankLevel() const;
    void turnOn();

class Car : public Vehicle {
    bool isTrunkOpen();

In this example, the Car class inherits from the Vehicle class, or, we can say Car derives from Vehicle. In C++ terminology, Vehicle is the base class, and Car is the derived class.

When defining a class, we can specify the classes it derives from by appending :, followed by one or more classes, separated by a comma:

class Car : public Vehicle, public Transport {

When specifying the list of classes to derive from, we can also specify the visibility of the inheritance – private, protected, or public.

The visibility modifier specifies who can know about the inheritance relationship between the classes.

The methods of the base class can be accessed as methods of the derived class based on the following rules:

Car car;

When the...
