The following is a list of Hello, world! programs.
Hello, world! programs make the text "Hello, world!" appear on a computer screen. It is usually the first program encountered when learning a programming language. Otherwise, it's a basic sanity check for an installation of a new programming language. If "Hello World" does not run, one must not try to develop complex programs before fixing the issues with the installation.
For even more languages have a look at the Hello World Collection.

ALGOL 68
[edit | edit source]The ALGOL 68 standard requires that reserved-words, types and operators are in a different typeface. Hence programs are typically published in either bold or an underline typeface, e.g.:
begin
printf($"Hello, world!"l$)
end
In the popular upper-case stropping convention for bold words:
BEGIN
printf($"Hello, world!"l$)
END
or using a wikitext like quote stropping, this is especially suitable on computers with only 6 bits per character (hence only have UPPERCASE):
'BEGIN'
PRINTF($"HELLO, WORLD!"L$)
'END'
or minimally using the "brief symbol" form of begin and end.
( printf($"Hello, world!"l$) )

APL
[edit | edit source] ∇R←HWΔPGM
[1] R←'HELLO WORLD!'
∇
- The Del on the first line begins function definition for the program named HWΔPGM. It is a niladic function (no parameters, as opposed to monadic or dyadic) and it will return an explicit result which allows other functions or APL primitives to use the returned value as input.
- The line labeled 1 assigns the text vector 'Hello, world!!' to the variable R
- The last line is another Del which ends the function definition.
When the function is executed by typing its name the APL interpreter assigns the text vector to the variable R, but since we have not used this value in another function, primitive, or assignment statement the interpreter returns it to the terminal, thus displaying the words on the next line below the function invocation.
The session would look like this
HWΔPGM Hello, world!!
While not a program, if you simply supplied the text vector to the interpreter but did not assign it to a variable it would return it to the terminal as output. Note that user input is automatically indented 6 spaces by the interpreter while results are displayed at the beginning of a new line.
'Hello, world!' Hello, world!!

BASIC
[edit | edit source]General
[edit | edit source]The following example works for any ANSI/ISO-compliant BASIC implementation, as well as most implementations built into or distributed with microcomputers in the 1970s and 1980s (usually some variant of Microsoft BASIC):
10 PRINT "Hello, world!"
20 END
Note that the "END" statement is optional in many implementations of BASIC.
Some implementations could also execute instructions in an immediate mode when line numbers are omitted. The following examples work without requiring a RUN instruction.
PRINT "Hello, world!"
? "Hello, world!"
Later implementations of BASIC allowed greater support for structured programming and did not require line numbers for source code. The following example works when RUN for the vast majority of modern BASICs.
PRINT "Hello, world!"
END
Again, the "END" statement is optional in many BASICs.

PICK/BASIC, DATA/BASIC, MV/BASIC
[edit | edit source]In addition to the ANSI syntax at the head of this article, most Pick operating system flavors of Dartmouth BASIC support extended syntax allowing cursor placement and other terminfo type functions for VDT's
X, Y positioning (colon ":" is the concatenation instruction):
PRINT @(34,12) : "Hello, world!"
Will display the string "Hello, world!" roughly centered in a 80X24 CRT.
Other functions:
PRINT @(-1) : @(34,12) : "Hello, world!"
Will clear the screen before displaying the string "Hello, world!" roughly centered in a 80X24 CRT.
Syntax variants:
CRT "Hello, world!"
Supporting the "@" functions above, the CRT statement ignores previous PRINTER statements and always sends output to the screen.
Some Pick operating system environments such as OpenQM support the DISPLAY variant of PRINT. This variant in addition to the "@" functions maintains pagination based upon the settings of the TERM variable:
DISPLAY "Hello, world!"

JavaFX Script
[edit | edit source]JavaFX Script was a scripting language formerly called F3 for Form Follows Function. It was discontinued by Oracle in 2010.
Frame {
title: "Hello World JavaFX"
width: 200
content: Label {
text: "Hello World"
}
visible: true
}
This program can also be written in this way:
var win = new Frame();
win.title = "Hello World JavaFX";
win.width = 200;
var label = new Label();
label.text = "Hello World";
win.content = label;
win.visible = true;
A simple console output version would be:
import java.lang.System;
System.out.println("Hello World");
Or even simpler (with a built-in function):
println("Hello World");
JavaScript
[edit | edit source]JavaScript does not have native (built in) input or output routines. Instead it relies on the facilities provided by its host environment.

PHP
[edit | edit source]PHP is a templating language and will echo any text not within PHP tags directly, so the simplest form is:
Hello, world!
Using actual PHP statements, it can be written:
<?php
echo 'Hello, world!';
?>
or use short-hand echoing, syntaxed as such:
<? echo "Hello, world!"?>
this will also work:
<?= "Hello, world!" ?>

Python
[edit | edit source]As a script/module
[edit | edit source]Python 2 and earlier
[edit | edit source]print "Hello, world!"
Python 3
[edit | edit source]print("Hello, world!")
This also works on Python 2.4 or later, but in an unintuitive way. In Python 3, it calls the print function with the string "Hello, world!". In Python 2, it executes the print statement with the expression ("Hello, world!"), which evaluates to the string "Hello, world!".
Any Python version
[edit | edit source]import sys
sys.stdout.write("Hello, world!\n")
In Python 2.6 or later:
from __future__ import print_function
print("Hello, world!")

[edit | edit source]Hello, world! Souffle by David Morgan-Mar.
Hello World Souffle. This recipe prints the immortal words "Hello world!", in a basically brute force way. It also makes a lot of food for one person. Ingredients. 72 g haricot beans 101 eggs 108 g lard 111 cups oil 32 zucchinis 119 ml water 114 g red salmon 100 g dijon mustard 33 potatoes Method. Put potatoes into the mixing bowl. Put dijon mustard into the mixing bowl. Put lard into the mixing bowl. Put red salmon into the mixing bowl. Put oil into the mixing bowl. Put water into the mixing bowl. Put zucchinis into the mixing bowl. Put oil into the mixing bowl. Put lard into the mixing bowl. Put lard into the mixing bowl. Put eggs into the mixing bowl. Put haricot beans into the mixing bowl. Liquefy contents of the mixing bowl. Pour contents of the mixing bowl into the baking dish. Serves 1.
Later Mike Worth wrote tastier and actually functional recipe.
Hello World Cake with Chocolate sauce. This prints hello world, while being tastier than Hello World Souffle. The main chef makes a " world!" cake, which he puts in the baking dish. When he gets the sous chef to make the "Hello" chocolate sauce, it gets put into the baking dish and then the whole thing is printed when he refrigerates the sauce. When actually cooking, I'm interpreting the chocolate sauce baking dish to be separate from the cake one and Liquify to mean either melt or blend depending on context. Ingredients. 33 g chocolate chips 100 g butter 54 ml double cream 2 pinches baking powder 114 g sugar 111 ml beaten eggs 119 g flour 32 g cocoa powder 0 g cake mixture Cooking time: 25 minutes. Pre-heat oven to 180 degrees Celsius. Method. Put chocolate chips into the mixing bowl. Put butter into the mixing bowl. Put sugar into the mixing bowl. Put beaten eggs into the mixing bowl.

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!
