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.

3. Built-in Data Types

Activity 3: Sign-Up Application


  1. Start by including the various headers that the application will need:
    // Activity 3: SignUp Application.
    #include <iostream>
    #include <string>
    #include <vector>
    #include <stdexcept>
  2. Next, define the class that will represent a record in the system. This is going to be a person, containing both a name and an age. Also, declare a vector of this type to store these records. A vector is used for the flexibility it gives in not having to declare an array size upfront:
    struct Person
        int age = 0;
        std::string name = "";
    std::vector<Person> records;
  3. Now, you can start adding some functions to add and fetch records; first, add. A record consists of a name and age, so write a function that will accept those two as parameters, create a record object, and add it to our record vector. Name this function AddRecord:
    void AddRecord...
