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:

    A trait no other nation seems to possess in quite the same degree that we do—namely, a feeling of almost childish injury and resentment unless the world as a whole recognizes how innocent we are of anything but the most generous and harmless intentions.
    Eleanor Roosevelt (1884–1962)

    These native villages are as unchanging as the woman in one of their stories. When she was called before a local justice he asked her age. “I have 45 years.” “But,” said the justice, “you were forty-five when you appeared before me two years ago.” “SeƱor Judge,” she replied proudly, drawing herself to her full height, “I am not of those who are one thing today and another tomorrow!”
    State of New Mexico, U.S. public relief program (1935-1943)
