Hello World Program

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:

    “The hotel was once where things coalesced, where you could meet both townspeople and travelers. Not so in a motel. No matter how you build it, the motel remains the haunt of the quick and dirty, where the only locals are Chamber of Commerce boys every fourth Thursday. Who ever heard the returning traveler exclaim over one of the great motels of the world he stayed in? Motels can be big, but never grand.”
    —William Least Heat Moon [William Trogdon] (b. 1939)

    “If you have a message you want to send to hell, give it to me; I’ll carry it!”
    —Administration in the State of Sout, U.S. public relief program (1935-1943)
