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.

13. Exception Handling in C++

Activity 13: Handling Exceptions


  1. Start with the sample program shown at the beginning of the activity:
    #include <iostream>
    using namespace std;
    int main()
        bool continue_flag;
            continue_flag = do_something();
        while (continue_flag == true);
        return 0;
  2. std::runtime_error, the exception signaled for sensor errors, is defined in the <stdexcept> header, so we need to include <stdexcept>. Depending on the compiler, we may also need to include the <exception> header:
    #include <exception>
    #include <stdexcept>
  3. In the main loop, replace the call to do_something() with a try...catch block. The skeleton try...catch block is shown here:
