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: “This problem can be fixed by making init a dependent name.”

A block of code is set as follows:

template <typename T>
struct parser : base_parser<T>
{
   void parse()
   {
      this->init(); // OK
      std::cout << "parse\n";
   }
};

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

fatal error: recursive template instantiation exceeded maximum
depth of 1024
use -ftemplate-depth=N to increase recursive template
instantiation depth

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “The capacity is 8, the size is 0, and the head and tail both point to index 0.”
