<language> One of the most used {object-oriented} languages, a
	superset of {C} developed primarily by {Bjarne Stroustrup}
	<bs@alice.att.com> at {AT&T} {Bell Laboratories} in 1986.

	In C++ a {class} is a user-defined {type}, syntactically a
	{struct} with {member functions}.  {Constructors} and
	{destructors} are member functions called to create or destroy
	{instances}.  A {friend} is a nonmember function that is
	allowed to access the private portion of a class.  C++ allows
	{implicit type conversion}, {function inlining}, {overloading}
	of operators and function names, and {default function
	arguments}.  It has {streams} for I/O and {references}.

	C++ 2.0 (May 1989) introduced {multiple inheritance},
	{type-safe linkage}, pointers to members, and {abstract
	classes}.

	C++ 2.1 was introduced in ["Annotated C++ Reference Manual",
	B. Stroustrup et al, A-W 1990].

<World-Wide Web> The {World-Wide Web} {search engine} that
	indexes the greatest number of web pages - over two billion by
	December 2001 and provides a free service that searches this
	index in less than a second.

	The site's name is apparently derived from "{googol}", but
	note the difference in spelling.

	The "Google" spelling is also used in "The Hitchhikers Guide
	to the Galaxy" by Douglas Adams, in which one of Deep
	Thought's designers asks, "And are you not," said Fook,
	leaning anxiously foward, "a greater analyst than the
	Googleplex Star Thinker in the Seventh Galaxy of Light and
	Ingenuity which can calculate the trajectory of every single
	dust particle throughout a five-week Dangrabad Beta sand
	blizzard?"

<messaging> /yoos'net/ or /yooz'net/ (Or "Usenet news", from
	"Users' Network") A distributed {bulletin board} system and
	the people who post and read articles thereon.  Originally
	implemented in 1979 - 1980 by Steve Bellovin, Jim Ellis, Tom
	Truscott, and Steve Daniel at Duke University, and supported
	mainly by {Unix} machines, it swiftly grew to become
	international in scope and, before the advent of the
	{World-Wide Web}, probably the largest decentralised
	information utility in existence.

	Usenet encompasses government agencies, universities, high
	schools, businesses of all sizes, and home computers of all
	descriptions.  In the beginning, not all Usenet hosts were on
	the Internet.  As of early 1993, it hosted over 1200
	{newsgroups} ("groups" for short) and an average of 40
	megabytes (the equivalent of several thousand paper pages) of
	new technical articles, news, discussion, chatter, and
	{flamage} every day.  By November 1999, the number of groups
	had grown to over 37,000.

	To join in you originally needed a {news reader} program but
	there are now several web gateways such as {Deja
	(http://www.deja.com/)}.  Several {web browsers} include news
	readers and {URLs} beginning "news:" refer to Usenet
	newsgroups.

	{Network News Transfer Protocol} is a {protocol} used to
	transfer news articles between a news {server} and a {news
	reader}.  The {uucp} {protocol} was sometimes used to transfer
	articles between servers, though this is probably rare now
	that most sites are on the {Internet}.

	{Stanford University} runs a service to send news articles by
	{electronic mail}.  Send electronic mail to
	<netnews@db.stanford.edu> with "help" in the message body.

[Mathematics] a fractional number n/d, where n and d are
	integers, n is the numerator and d is the denominator.  The
	set of all rational numbers is usually called Q.
	Computers do not usually deal with rational numbers but
	instead convert them to {real} numbers which are represented
	(approximately in some cases) as {floating-point} numbers.
	Compare {irrational}.
