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.

Bitwise Operators

Bitwise operations are those that work on individual bits, such as shifting a bit to the left, and for this, we have a suite of specialized operators known as bitwise operators. We're not going to go into too much detail here—a full discussion on bitwise operators is for another day. However, we will take a quick look at what bitwise operators we have available to us, along with some quick examples of their use. This will give you some preliminary understanding so that when you do come across them later, they'll be familiar.

Note

Remember, a bit (that is, a binary digit) is the most fundamental unit of data in a computer. With two possible values, either 1 or 0, all data is stored in bits. The smallest addressable unit of data on a machine is a byte, which is made up of 8 bits, so bitwise operations allow us to manipulate bits individually.

In the following examples, we're going to be working with bitsets. This is a simple...
