โปรแกรมเฮลโลเวิลด์ เป็นโปรแกรมคอมพิวเตอร์พื้นฐานที่ทำการแสดงผลคำว่า "Hello, World!" บน ซึ่งเป็นหนึ่งในโปรแกรมที่ง่ายที่สุดเท่าที่จะเป็นไปได้ในการเขียนภาษาโปรแกรมต่าง ๆ และมักถูกใช้เป็นตัวอย่างที่ง่ายที่สุดในการแสดงวากยสัมพันธ์ของภาษาโปรแกรมหนึ่ง ๆ โดยมักจะเป็นโปรแกรมแรกที่ผู้เริ่มต้นเขียนโปรแกรมเขียนออกมา นอกจากนี้ โปรแกรมเฮลโลเวิลด์ ยังสามารถใช้เพื่อตรวจสอบเบื้องต้นได้ว่า เครื่องมือของภาษาโปรแกรมถูกติดตั้งอย่างสมบูรณ์หรือไม่

ประวัติ

โปรแกรมเฮลโลเวิลด์โปรแกรมแรกเกิดขึ้น จากหนังสือการเขียนโปรแกรมภาษาซี แต่งโดย และ เดนนิส ริตชี ตีพิมพ์ในปี พ.ศ. 2521 (ค.ศ. 1978) โดยตัวอย่างโปรแกรมมาจาก กระดาษจดข้อมูลของไบรอันขณะที่ทำงานที่ (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

or using prime stropping suitable for :

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

General

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 ) :

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 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.

JavaScript and

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".

This uses the 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; }

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>

XUL

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

(simple)

<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.

=== HTML 4.01 Strict=== (full)

<!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.
