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.

Introduction

Previous chapters introduced C++ flow-of-control statements and variable declarations. We have had a taste of object-oriented programming and created data structures out of dynamic variables. In this chapter, we turn our attention to how C++ can help a developer handle situations that arise when something unexpectedly goes wrong in a program.

An invalid number input by the user, an unanticipated timeout awaiting a response, and a logic error are all examples of events in a program. Some of these events, such as the input error, may occur so frequently or predictably that they must be anticipated and handled, or else the program will be unusable. Other events, such as the timeout, happen rarely, and never when the program and the system within which it runs are working perfectly. Still other events, such as the logic error, are never meant to happen at all, but sometimes they do anyway.

The user input error event is an expected event. It is handled with specific...
