The C++ Workshop

By: Dale Green, Kurt Guntheroth, Shaun Ross Mitchell

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.

1. Your First C++ Application

Activity 1: Write Your Own C++ Application

Solution:

  1. Define your age bracket thresholds using #defines.
  2. Define a name for each group using #defines.

    Here is the code required for steps 1 and 2:

    // Activity 1. 
    #include <iostream>
    #include <string>
    #define GROUP_1_THRESHOLD 12
    #define GROUP_2_THRESHOLD 28
    #define GROUP_1_NAME "Group A"
    #define GROUP_2_NAME "Group B"
    #define GROUP_3_NAME "Group C"
  3. Output a text string asking the user for their name and capture the response in a variable.
  4. Output text asking the user for their age and capture the response in a variable.
  5. Write a function that will accept age as a parameter and return the appropriate group name.
  6. Output the user's name, and the group that they have been assigned to.

    Here is the code required to perform steps 3-6:

    std::string GetGroup(int age);
    int main()
    {
        std::string name = "";
    &...
