Hello World?

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, and to verify that a language or system is operating correctly.

The first known instance of the usage of the words "hello" and "world" together in computer literature occurred in Kernighan's 1972 "Tutorial Introduction to the Language" with the following code:

 main( ) {
   extrn a, b, c;
   putchar(a); putchar(b); putchar(c); putchar('!*n');
 a 'hell';
 b 'o, w';
 c 'orld';
