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:
“What a world is this! What is there in it desirable? The good we hope for so strangely mixed, that one knows not what to wish for! And one half of mankind tormenting the other, and being tormented themselves in tormenting!”
—Samuel Richardson (1689–1761)
“On our streets it is the sight of a totally unknown face or figure which arrests the attention, rather than, as in big cities, the strangeness of occasionally seeing someone you know.”
—For the State of Vermont, U.S. public relief program (1935-1943)
