The C++ Workshop

Overview of this book

C++ is the backbone of many games, GUI-based applications, and operating systems. Learning C++ effectively is more than a matter of simply reading through theory, as the real challenge is understanding the fundamentals in depth and being able to use them in the real world. If you're looking to learn C++ programming efficiently, this Workshop is a comprehensive guide that covers all the core features of C++ and how to apply them. It will help you take the next big step toward writing efficient, reliable C++ programs. The C++ Workshop begins by explaining the basic structure of a C++ application, showing you how to write and run your first program to understand data types, operators, variables and the flow of control structures. You'll also see how to make smarter decisions when it comes to using storage space by declaring dynamic variables during program runtime. Moving ahead, you'll use object-oriented programming (OOP) techniques such as inheritance, polymorphism, and class hierarchies to make your code structure organized and efficient. Finally, you'll use the C++ standard library?s built-in functions and templates to speed up different programming tasks. By the end of this C++ book, you will have the knowledge and skills to confidently tackle your own ambitious projects and advance your career as a C++ developer.

Polymorphism

We've now seen how we can use inheritance to create generic, base versions of objects, then specialize them in derived classes. Some of the many benefits of this include reduced code repetition, the ability to implement a common interface, and polymorphism.

Polymorphism allows us to call different implementations of the same function depending on which inheriting object we're calling the function on. We can do this because we can store derived types in a pointer variable of their base type. When we do this, we limit ourselves to only being able to access the members declared in the base, but when it's called, we'll get the implementations of the derived class.

Let's take a look at some code to see this in action:

// Polymorphism. 
#include <iostream>
#include <string>
class MyClassA 
{
public:
    virtual std::string GetString() = 0;
};
class MyClassB: public MyClassA 
{
public:
