Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Here, the printing of Hello, World is tasked to the main function."

A block of code is set as follows:

#include <iostream>
// Program prints out "Hello, World" to screen
int main()
{
std::cout<< "Hello, World."<<std::endl;
return 0;
} 

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

int main() {
    //init game objects
        while (window.isOpen()) {
            // Handle Keyboard events
            // Update Game Objects in the scene
    window.clear(sf::Color::Red);
    // Render Game Objects
    window.display();
        }
        return 0;
    }

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "In Input and under Linker, type the following .lib files."
