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.

Activity 23: Creating Game Characters

  1. Create a Character class that has a public method moveTo that prints Moved to position:

    class Character {
      public:
        void moveTo(Position newPosition) {
          position = newPosition;
          std::cout << “Moved to position “ << newPosition.positionIdentifier << std::endl;
        }
      private:
        Position position;
    };
  2. Create a struct named Position:

    struct Position {
      // Fields to describe the position go here
      std::string positionIdentifier;
    };
  3. Create two classes Hero and Enemy that are derived from the class Character:

    // Hero inherits publicly from Character: it has
    // all the public member of the Character class.
    class Hero : public Character {
    
    };
    
    // Enemy inherits publicly from Character, like Hero
    class Enemy : public Character {
    
    };
  4. Create a class Spell with the constructor that prints the name of the person casting the spell:

    class Spell {
    public:
        Spell(std::string name) : d_name(name) {}
    ...
