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.

Relational Operators

Relational operators allow us to compare values with one another. We could, for example, check whether one value was greater than another, or if two values were equal. These operators not only work on integer values but also on collections and objects. There are two fundamental relationships that are often checked for: equality and comparison.

Equality

The relational operators that are used to determine the equality of two values are == and !=; that is, equal and not equal, respectively. A value is placed on either side of the operators, referred to as LHS on the left and RHS on the right, and it's these two values that are compared. A single Boolean value is returned that denotes whether the equality check was true or not.

The two operators can be used as follows:

// Relational operators. Equality. 
#include <iostream>
#include <string>
int main()
{
    int myInt1 = 1;
    int myInt2 = 1;
