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.

Arithmetic Operators

Arithmetic operators are those that allow us to perform mathematical operations on our data. These are very self-explanatory and straightforward to use as, aside from the modulus operator, they have the same symbol that we'd use for everyday mathematics. For example, in order to add a number, you simply use the "+" sign as you would anywhere. Generally, these operators are going to be used with numeric data types, however, there's nothing stopping a type from implementing this operator. This will be covered as the final topic of the chapter.

Let's take a quick look at our four basic operators: addition, subtraction, multiplication, and division. As stated previously, these four operators have the same symbols that you'd use day to day, so they should be familiar. The following example implements all four types of arithmetic operators:

// Arithmetic operators. 
#include <iostream>
#include <string>
int main() 
{
