Hello World Program
A "Hello world" program is a computer program that outputs "Hello, world" on a display device. Because it is typically one of the simplest programs possible in most programming languages, it is by tradition often used to illustrate to beginners the most basic syntax of a programming language, or to verify that a language or system is operating correctly.
In a device that does not display text, a simple program to produce a signal, such as turning on an LED, is often substituted for "Hello world" as the introductory program.

Famous quotes containing the words world and/or program:
“How should the world be luckier if this house,
Where passion and precision have been one
Time out of mind, became too ruinous
To breed the lidless eye that loves the sun?”
—William Butler Yeats (1865–1939)
““Why visit the playhouse to see the famous Parisian models, ... when one can see the French damsels, Norma and Diana? Their names have been known on both continents, because everything goes as it will, and those that cannot be satisfied with these must surely be of a queer nature.””
—For the City of New Orleans, U.S. public relief program (1935-1943)
