โปรแกรมเฮลโลเวิลด์

โปรแกรมเฮลโลเวิลด์โปรแกรมแรกเกิดขึ้น จากหนังสือการเขียนโปรแกรมภาษาซี แต่งโดยไบรอัน เคอร์นิงแฮน และ เดนนิส ริตชี ตีพิมพ์ในปี พ.ศ. 2521 (ค.ศ. 1978) โดยตัวอย่างโปรแกรมมาจาก กระดาษจดข้อมูลของไบรอันขณะที่ทำงานที่ เบลล์แล็บ (Bell Laboratories) ปี พ.ศ. 2517 (ค.ศ. 1974) ตัวอย่างในหนังสือ พิมพ์ข้อความว่า "hello, world" (โดยไม่ใช้ตัวพิมพ์ใหญ่และเครื่องหมายตกใจ ซึ่งได้ถูกเพิ่มมาในภายหลัง)

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

การเขียนคำนี้ มีการใช้งานโดยเขียนหลายแบบคือ ตัวอักษร H ใหญ่ และ h เล็ก ขณะเดียวกับ W ใหญ่ และ w เล็ก รวมถึงการเขียนเครื่องหมาย และแบบไม่มีเครื่องหมาย

การเขียนชุดคำสั่งนี้ในขณะที่บางโปรแกรมสามารถใช้คำสั่งได้อย่างเรียบง่าย ในขณะที่บางโปรแกรมต้องใช้คำสั่งซับซ้อนในการแสดงผล โดยเฉพาะอย่างยิ่งที่ใช้ GUI โปรแกรมเฮลโลเวิลด์มีประโยชน์ในการทดสอบว่าคอมไพเลอร์และส่วนต่างๆหลักของโปรแกรมทำงานได้ การรวบรวมคำสั่ง "hello world" ในภาษาโปรแกรมต่าง ๆ ถูกใช้ในการช่วยเรียน และการเปรียบเทียบการใช้งานของภาษาต่างๆ

message "Hello, World!" with style = popup;

REPORT ZELLO.WRITE 'Hello, World!'.

WRITE "Hello, world!"

with Ada.Text_IO;procedure Hello isbegin   Ada.Text_IO.Put_Line ("Hello, world!") ;end Hello;

For explanation see wikibooks:Ada Programming:Basic.

In the popular upper-case stropping convention for bold words:

BEGIN    print (("Hello, World!", newline))END

or using prime stropping suitable for punch cards:

'BEGIN'    PRINT (("HELLO, WORLD!", NEWLINE))'END'

or minimally using the short form of begin and end, and implied newline at program termination:

( print ("Hello, World!") )

PROC main ()   WriteF ('Hello, World!') ;ENDPROC

'Hello World'

See also GUI section.

return "Hello World!"

<%Response.Write ("Hello World")%>

or simply:

<%="Hello World" %>

Response.Write ("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

Such implementations of BASIC 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.

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 secondLOOPEND

sub main    print "Hello, World"end sub

On TI calculators of the TI-80 through TI-86 range:

:Disp "HELLO, WORLD!"           or:Output (x,y,"HELLO, WORLD!")    or:Text (x,y,"HELLO, WORLD!")      or:Text (-1,x,y,"HELLO, WORLD!")   ;only on the 83+ and higher

or simply

:"HELLO, WORLD!"

On TI-89/TI-92 (+) /Voyage 200 calculators:

:hellowld ():Prgm:Disp "Hello, world!":EndPrgm

Sub Main  MsgBox "Hello World!"End Sub

Module HelloWorldApp  Sub Main ()     System.Console.WriteLine ("Hello, world!")  End SubEnd Module

or, defined differently,

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!") ;   }}

Java applets work in conjunction with HTML files.

<HTML><HEAD><TITLE>Hello World</TITLE></HEAD><BODY>HelloWorld Program says:<APPLET CODE="HelloWorld.class" WIDTH=600 HEIGHT=100></APPLET>

</BODY></HTML>

import import public class HelloWorld extends Applet {  public void paint (Graphics g) {    g.drawString ("Hello, world!", 100, 50) ;  }}

JavaScript (an implementation of ECMAScript) is a client-side scripting language used in HTML files. The following code can be placed in any HTML file: { alert ("Hello, world!") ; } //--></script> <a href="#" onclick="helloWorld () ; return false;">Hello World Example</a>

An easier method uses JavaScript implicitly, directly calling the reserved alert function. Cut and paste the following line inside the <body> .... </body> HTML tags.

<a href="#" onclick="alert ('Hello, world!') ; return false;">Hello World Example</a>

An even easier method involves using popular browsers' support for the virtual 'javascript' protocol to execute JavaScript code. Enter the following as an Internet address (usually by pasting into the address box) :

javascript:alert ('Hello, world!') ;

There are many other ways:

javascript:document.write ('Hello, world!\n') ;

This creates a window labeled "Hello world" with a button labeled "Hello world".

hello:hello..l:"Hello world"hello..c:`button`show$`hello

This uses the Windows API to create a full window containing the text. Another example below uses the built-in MessageBox function instead.

#include <windows.h>LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM) ;char szClassName[] = "MainWnd";int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine,                   int nCmdShow){  HWND hwnd;  MSG msg;  WNDCLASSEX wincl;  wincl.cbSize = sizeof (WNDCLASSEX) ;  wincl.cbClsExtra = 0;  wincl.cbWndExtra = 0;  wincl.style = 0;  wincl.hInstance = hInstance;  wincl.lpszClassName = szClassName;  wincl.lpszMenuName = NULL; //No menu  wincl.lpfnWndProc = WindowProcedure;  wincl.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1) ; //Color of the window  wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION) ; //EXE icon  wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION) ; //Small program icon  wincl.hCursor = LoadCursor (NULL, IDC_ARROW) ; //Cursor  if (!RegisterClassEx (&wincl))        return 0;  hwnd = CreateWindowEx (0, //No extended window styles        szClassName, //Class name        "", //Window caption        WS_OVERLAPPEDWINDOW & ~WS_MAXIMIZEBOX,        CW_USEDEFAULT, CW_USEDEFAULT, //Let Windows decide the left and top                                      //positions of the window        120, 50, //Width and height of the window,        NULL, NULL, hInstance, NULL) ;  //Make the window visible on the screen  ShowWindow (hwnd, nCmdShow) ;  //Run the message loop  while (GetMessage (&msg, NULL, 0, 0) >0)  {        TranslateMessage (&msg) ;        DispatchMessage (&msg) ;  }  return msg.wParam;}LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message,                                 WPARAM wParam, LPARAM lParam){  PAINTSTRUCT ps;  HDC hdc;  switch (message)  {  case WM_PAINT:        hdc = BeginPaint (hwnd, &ps) ;        TextOut (hdc, 15, 3, "Hello, world!", 13) ;        EndPaint (hwnd, &ps) ;        break;  case WM_DESTROY:        PostQuitMessage (0) ;        break;  default:        return DefWindowProc (hwnd, message, wParam, lParam) ;  }  return 0;}

Or, much more simply:

#include <windows.h>int WINAPI WinMain (HINSTANCE hInst, HINSTANCE hPrevInstance, LPSTR lpCmdLine,                   int nCmdShow){    MessageBox (NULL, "Hello, world!", "", MB_OK) ;    return 0;}

<job id="HelloWorld">        <script language="VBScript">                WScript.Echo "Hello, world!"        </script></job>

<job id="HelloWorld">        <script language="JScript">                WScript.Echo ( "Hello, world!" ) ;        </script></job>

There are many ways to do this in XSL, the simplest being:

<xsl:template match="/">  <xsl:text>Hello, world!</xsl:text></xsl:template>

If nested similar to the HTML version, it would be:

<xsl:template match="/">  <html>    <body>      <h1>Hello, world!</h1>    </body>  </html></xsl:template>

Type the following in a text file (e.g. hello.world.xul) and then open with Mozilla Firefox.

<window xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">  <box align="center" pack="center" flex="1">    <description>Hello, world</description>  </box></window>

<html><body><h1>Hello, world!</h1></body></html>

<html> and <body>-tags are not necessary for informal testing. You could even use the following:

<pre>Hello, World!</pre>

or simply write it as text without tags.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Strict//EN" "http://www.w3.org/TR/html4/strict.dtd"><html>   <head>    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">    <title>Hello, World!</title>   </head>   <body>    <p>Hello, world!</p>   </body></html>

Notice that the HEAD tag is optional and could be omitted.The first paragraph of the W3C Recommendation on The global structure of an HTML document also features this example.
