Overview of this book

This book is all about offering you a fun introduction to the world of game programming, C++, and the OpenGL-powered SFML using three fun, fully-playable games. These games are an addictive frantic two-button tapper, a multi-level zombie survival shooter, and a split-screen multiplayer puzzle-platformer. We will start with the very basics of programming, such as variables, loops, and conditions and you will become more skillful with each game as you move through the key C++ topics, such as OOP (Object-Orientated Programming), C++ pointers, and an introduction to the Standard Template Library. While building these games, you will also learn exciting game programming concepts like particle effects, directional sound (spatialization), OpenGL programmable Shaders, spawning thousands of objects, and more.

C++ strings

In the previous chapter we briefly mentioned strings and we learned that a string can hold alphanumeric data in anything from a single character to a whole book. We didn't look at declaring, initializing, or manipulating strings. So let's do that now.

Declaring strings

Declaring a string variable is simple. We state the type, followed by the name:

String levelName; 
String playerName;

Once we have declared a string we can assign a value to it.

Assigning a value to strings

To assign a value to a string, as with regular variables, we simply put the name, followed by the assignment operator, then the value:

levelName = "Dastardly Cave"; 
playerName = "John Carmack";

Note that the values need to be enclosed in quotation marks. As with regular variables we can also declare and assign values in a single line:

String score = "Score = 0"; 
String message = "GAME OVER!!";

This is how we can change our string variables.

Manipulating strings...
