Conventions used

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

Code in text: 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: “The –Werror parameter turns these warnings into errors and will force the developer to inspect and fix each case that generates a compiler warning before compilation can succeed.”

A block of code is set as follows:

if(!a && !b) {}

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

main:
.LFB1
    Movl    $100, %edi
    Call    _Z9factorialj

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

SpecificRuntimeExample::placeOrder()
SpecificCRTPExample::actualPlaceOrder()
