Computer Programming/Hello world - Wikibooks, open books for an open world
- ️Tue Mar 20 2007
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.
It should be noted that the 4DOS/4NT batch language is a superset of the MS-DOS batch language.
message "Hello, world!" with style = popup;
REPORT ZHELLO. START-OF-SELECTION. WRITE "Hello, world!".
The example below makes use of the singleton pattern and outputs the text in a message box instead of a classic list output.
REPORT ZHELLO. CLASS lcl_hello DEFINITION CREATE PRIVATE FINAL. PUBLIC SECTION. CLASS-DATA self TYPE REF TO lcl_hello READ-ONLY. CLASS-METHODS class_constructor. METHODS say_hello. PRIVATE SECTION. CONSTANTS con_hello_world TYPE c LENGTH 13 VALUE 'Hello, World!'. ENDCLASS. CLASS lcl_hello IMPLEMENTATION. METHOD class_constructor. CREATE OBJECT lcl_hello=>self. ENDMETHOD. METHOD say_hello. MESSAGE con_hello_world TYPE 'I'. ENDMETHOD. ENDCLASS. START-OF-SELECTION. lcl_hello=>self->say_hello( ).
WRITE "Hello, world!"
This will output to the output window only, which an end user would not see.
This version will be visible to the end user.
var helloWorld:TextField = this.createTextField( "helloWorld", this.getNextHighestDepth(), 1, 1, 100, 20 ); helloWorld.text = "Hello, world!";
package { public class HelloWorld { public function HelloWorld() { trace("Hello, world!"); } } }
with Ada.Text_IO; procedure Hello is begin Ada.Text_IO.Put_Line ("Hello, world!"); end Hello;
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($"Hello, world!"l$) )
PROC main()
WriteF('Hello, world!');
ENDPROC
This program sends the message out via the Diagnostics Interface after start-up.
program_name = 'Hello' define_start send_string 0,'Hello World!'
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE project> <project default="helloworld"> <target name="helloworld"> <echo message="Hello, World!" /> </target> </project>
∇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!!
or:
display dialog "Hello, world!"
<% Response.Write("Hello, world!") %>
- or simply:
// in the page behind using C# protected void Page_Load(object sender, EventArgs e) { Response.Write("Hello, world!"); }
' in the page behind using VB.NET Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Response.Write("Hello, world!") End Sub
// ASPX Page Template <asp:Literal ID="Literal1" runat="server" Text="Hello World!"></asp:Literal>
or
<asp:Label ID="Label1" runat="server" Text="Hello World"></asp:Label>
or

This is the first known Hello, world! program ever written:[1]
main( ) { extrn a, b, c; putchar(a); putchar(b); putchar(c); putchar('!*n'); } a 'hell'; b 'o, w'; c 'orld';
Also known as Triton Tools on older versions. On Baan ERP you can create a program on 3GL or 4GL mode.
function main()
{
message("Hello, world!")
}

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.
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.
Print "Hello, world!" WaitKey
or
TEXT 0,0,"Hello, world!" WAIT KEY
Note: In the "classic" Dark Basic the WAIT KEY command is optional as the console goes up when the program has finished.
PRINT "Hello World" SLEEP END
or
or
or
'without a newline ? "Hello World";
AddText "Hello, world!" DrawScreen WaitKey
10 PRINT "Hello, World!" 20 END
To write to the main window:
Or drawn in a graphics window:
nomainwin open "Hello, world!" for graphics as #main print #main, "place 50 50" print #main, "\Hello, world!" print #main, "flush" wait
TextWindow.WriteLine("Hello, world!")
DEBUG "Hello, world!", CR
or, the typical microcontroller Hello, world! program equivalent with the only output device present being a light-emitting diode (LED) (in this case attached to the seventh output pin):
DO HIGH 7 'Make the 7th pin go high (turn the LED on) PAUSE 500 'Sleep for half a second LOW 7 ' Make the 7th pin go low (turn the LED off) PAUSE 500 'Sleep for half a second LOOP END
sub main print "Hello, world!" end sub
OpenConsole() PrintN("Hello, world!") Input()
or
MessageRequester("Hello, World","Hello, World")
or
PRINT "Hello, World" END
Same for QBasic
On TI calculators of the TI-80 through TI-86 range:
:Disp "Hello, world! (note the optional ending quotes) :Output(X,Y,"Hello, world! (note the optional ending parenthesis) :Text(X,Y,"Hello, world! (writes to the graph rather than home screen) :Text(-1,X,Y,"Hello, world! (only on the 83+ and higher, provides larger text, home screen size) :"Hello, world! (last line of program only)
Note: "!" character is not on the keypad. It can be accessed from "Catalog" menu, "Probability" menu, or "Math" menu (as factorial notation).
On TI-89/TI-89 Titanium/TI-92(+)/Voyage 200 calculators:
:hellowld() :Prgm :Disp "Hello, world!" :EndPrgm
Public Sub Main() Debug.Print "Hello, world!" End Sub
or
Public Sub Main() MsgBox "Hello, world!" End Sub
or
Private Sub Form_Activate() Print "Hello, world!" End Sub
Alternatively, copy this into a New Form:
Private Sub Form_Click() Form1.Hide Dim HelloWorld As New Form1 HelloWorld.Width = 2500: HelloWorld.Height = 1000: HelloWorld.Caption = "Hello, world!": HelloWorld.CurrentX = 500: HelloWorld.CurrentY = 75 HelloWorld.Show: HelloWorld.Font = "Tahoma": HelloWorld.FontBold = True: HelloWorld.FontSize = 12: HelloWorld.Print "Hello, world!" End Sub
Module HelloWorldApp Sub Main() System.Console.WriteLine("Hello, world!") End Sub End Module
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!"

@echo off set hellostring=Hello World! echo %hellostring%

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):
JavaScript does not have native (built in) input or output routines. Instead it relies on the facilities provided by its host environment.
Using a standard Web browser's document object
document.write('Hello, World!');
or with an alert, using a standard Web browser's window object (window.alert)

(with the standard command.com interpreter. The @ symbol is optional and prevents the system from repeating the command before executing it. The @ symbol must be omitted on versions of MS-DOS prior to 3.0.). It's very common for batchfiles to start with two lines of "@echo off" and "cls".

@echo off cls echo Hello, world!

The easiest way to get Nemerle print "Hello, world!" would be that:
System.Console.WriteLine("Hello, world!");
however, in bigger applications the following code would be probably more useful:
using System.Console; module HelloWorld { Main():void { WriteLine("Hello, world!"); } }

PHP is a templating language and will echo any text not within PHP tags directly, so the simplest form is:
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:
int main() { write("Hello, world!\n"); return 0; }
T:Hello, world!
set serveroutput on size 1000000; -- this is a SQL*Plus command to enable the output buffer begin dbms_output.put_line('Hello, world!'); end;

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!".
import sys sys.stdout.write("Hello, world!\n")
In Python 2.6 or later:
from __future__ import print_function print("Hello, world!")
import __hello__ import __phello__
from math import cos, sin def f(x): return int(round(96.75 + -21.98*cos(x*1.118) + 13.29*sin(x*1.118) + -8.387*cos(2*x*1.118)\ + 17.94*sin(2*x*1.118) + 1.265*cos(3*x*1.118) + 16.58*sin(3*x*1.118)\ + 3.988*cos(4*x*1.118) + 8.463*sin(4*x*1.118) + 0.3583*cos(5*x*1.118)\ + 5.878*sin(5*x*1.118))) print("".join([chr(f(x)) for x in range(12)]))
'Hello, world!' (with quotation marks) can be attained through:
#!/usr/local/bin/python print("Content-type: text/html\n\n") print("Hello World!")

Functional equivalent of C# program below.
In C# 10, using the MessageBox class, with top-level statements enabled (default), the code is only one line:
MessageBox.Show("Hello, world!");
Alternatively, one could write the dialog box from the scratch:
public class HelloWorldForm : Form { public static void Main() { Application.EnableVisualStyles(); Application.Run(new HelloWorldForm()); } public HelloWorldForm() { Label label = new Label(); label.Text = "Hello, world!"; label.Location = new Point(40, 30); this.Controls.Add(label); Button button = new Button(); button.Text = "OK"; button.Location = new Point(50, 55); this.Controls.Add(button); button.Click += new EventHandler(button_Click); } private void button_Click(Object sender, EventArgs e) { Application.Exit(); } }
The simplest way to achieve this is with the built in message function that is similar to the windows messageBox().

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.

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!
[Exeunt]

The OO language looks like C.
use System.Windows.Forms; class HelloWorld extends System.Windows.Forms { protected: String hw; construct HelloWorld() { this.hw = 'Hello, world!'; } public void function show() { MessageBox.show(this.hw, ''); } }
Copy this and paste in ChatGPT, on a new chat:
Output: Hello, world!
A longer version, which still prints "Hello, world!":
CreateBuf: $Hello$
$Hello$: {
[H]
[e]
[l]
[l]
[o]
[,]
[32] @ The ASCII value for space
[w]
[o]
[r]
[l]
[d]
[!]
}
OpenBuf: $Hello$
JoinAllChars: $Hello$ => $Hello2$
Output: $Hello2$
CloseBuf: $Hello$
Note: The first method is tested and it's working. I don't know about the second one!
