The Hello World Collection

Hello World! "Hello World" is the first program one usually writes when learning a new programming language. Having first been mentioned in Brian Kernighan's tutorial to the B programming language, it became widely known through Kernighan & Ritchie's 1978 book that introduced "The C Programming Language", where it read like this:

main() {
    printf("hello, world\n");
}

Since then, Hello World has been implemented in just about every programming language on the planet. This collection includes 603 Hello World programs in as many more-or-less well known programming languages, plus 78 human languages.

The programs in this collection are intended to be as minimal as possible in the respective language. They are meant to demonstrate how to output Hello World as simply as possible, not to show off language features. For a collection of programs that tell more about what programming in the languages actually is like, have a look at the 99 Bottles of Beer collection.

The Hello World Collection, started in 1994, was compiled with help from many people around the world. It is the biggest collection of Hello World programs on the Internet, and the only one collecting human languages as well. To contribute, send your program to info@helloworldcollection.de. Begin your contribution with a comment in the respective language. Real programming languages only please.

@*A Simple Example.
This is a trivial example of a \.{CWEB} program.
It is, of course, the classic "hello, world"
program we all know and love:

@c
@<Header files needed by the program@>@;
@#
main(void)
{
   @<Print the message |"hello, world"|@>@;
}

@ Naturally, we use |printf| to do the dirty work:

@<Print the message |"hello, world"|@>=
printf("hello, world\n");

@ The prototype for |printf| is in the standard
header, \.{<stdio.h>}.

@<Header files needed by the program@>=
#include <stdio.h>

The Infamous Hello World Program in Shakespeare.

Romeo, a young man with a remarkable patience.
Juliet, a likewise young woman of remarkable grace.
Ophelia, a remarkable woman much in dispute with Hamlet.
Hamlet, the flatterer of Andersen Insulting A/S.


                    Act I: Hamlet's insults and flattery.

                    Scene I: The insulting of Romeo.

[Enter Hamlet and Romeo]

Hamlet:
 You lying stupid fatherless big smelly half-witted coward!
 You are as stupid as the difference between a handsome rich brave
 hero and thyself! Speak your mind!

 You are as brave as the sum of your fat little stuffed misused dusty
 old rotten codpiece and a beautiful fair warm peaceful sunny summer's
 day. You are as healthy as the difference between the sum of the
 sweetest reddest rose and my father and yourself! Speak your mind!

 You are as cowardly as the sum of yourself and the difference
 between a big mighty proud kingdom and a horse. Speak your mind.

 Speak your mind!

[Exit Romeo]

                    Scene II: The praising of Juliet.

[Enter Juliet]

Hamlet:
 Thou art as sweet as the sum of the sum of Romeo and his horse and his
 black cat! Speak thy mind!

[Exit Juliet]

                    Scene III: The praising of Ophelia.

[Enter Ophelia]

Hamlet:
 Thou art as lovely as the product of a large rural town and my amazing
 bottomless embroidered purse. Speak thy mind!

 Thou art as loving as the product of the bluest clearest sweetest sky
 and the sum of a squirrel and a white horse. Thou art as beautiful as
 the difference between Juliet and thyself. Speak thy mind!

[Exeunt Ophelia and Hamlet]


                    Act II: Behind Hamlet's back.

                    Scene I: Romeo and Juliet's conversation.

[Enter Romeo and Juliet]

Romeo:
 Speak your mind. You are as worried as the sum of yourself and the
 difference between my small smooth hamster and my nose. Speak your
 mind!

Juliet:
 Speak YOUR mind! You are as bad as Hamlet! You are as small as the
 difference between the square of the difference between my little pony
 and your big hairy hound and the cube of your sorry little
 codpiece. Speak your mind!

[Exit Romeo]

                    Scene II: Juliet and Ophelia's conversation.

[Enter Ophelia]

Juliet:
 Thou art as good as the quotient between Romeo and the sum of a small
 furry animal and a leech. Speak your mind!

Ophelia:
 Thou art as disgusting as the quotient between Romeo and twice the
 difference between a mistletoe and an oozing infected blister! Speak
 your mind!

The History of the Hello World Collection

The Hello World Collection was started on 3-Oct-1994 as a simple text file. After some posts on a German BBS network, it was put on the World Wide Web on 30-Dec-1999 as part of a private homepage. On 14-Sep-2014 it moved to its own domain, helloworldcollection.de, by which time it had accumulated 21 Reddit points, 35 LinkedIn shares, 156 Google Plus's, 450 Tweets, and 1947 Facebook likes. It got its own Twitter account, @HelloWorldClctn, on 31-Jan-2015.

The Collection exceeded 200 entries on 14-Jul-2005, 300 on 6-Dec-2006, 400 on 27-Jul-2008, 500 on 27-Dec-2015 (after a four-year hiatus which ended in 2014), and 600 on 16-Apr-2020.

The Collection is administered as a bunch of text files which are compiled into this single HTML file by a bash script, originally written for Linux, then used under Cygwin on Windows, then for several years on macOS, now on Linux again.

By the way, this site is the original Hello World Collection. Throughout the Web, you can find many copies of various versions of this file, not all of which give proper credit to those who compiled and contributed to it over the years. The official address of the Hello World Collection is helloworldcollection.de.
