Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The initialize() method initializes the deque iterator pos to the first data element stored within deque."

A block of code is set as follows:

#include <iostream>

int main ( ) {

        const int x = 5, y = 5;

        static_assert ( 1 == 0, "Assertion failed" );
        static_assert ( 1 == 0 );
        static_assert ( x == y );

        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:

#include <iostream>
#include <thread>
#include <mutex>
#include "Account.h"
using namespace std;

enum ThreadType {
  DEPOSITOR,
  WITHDRAWER
};

mutex locker;

Any command-line input or output is written as follows:

g++ main.cpp -std=c++17
./a.out

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: " You need to create a new project named MathApp by navigating to New Project | Visual Studio | Windows | Win32 | Win32 Console Application."
