MsgBox(1,'','Hello, world!')BEGIN { print "Hello, world!" }echo 'Hello, world!'
或者：
printf 'Hello, world!\n'
传统版 BASIC（例如 GWBASIC）：
10 PRINT "Hello, world!"20 END
或：
10 PRINT "Hello, world!"
或在提示符输入：
? "Hello, world!"
现代版 BASIC（例如 Quick BASIC）：
Print "Hello, world!"
以下的语句，在 Quick BASIC 中同样有效：
? "Hello, world!"

#include <stdio.h>int main(void){ puts("Hello, world!"); return 0;}console.log 'Hello, world!'
或者：
alert 'Hello, world!'
#include <iostream>int main(){ std::cout << "Hello, world!" << std::endl; return 0;}或者：
#include <iostream>using namespace std;int main(){ cout << "Hello, world!" << endl; return 0;}int main(){ System::Control::WriteLine("Hello, world!");}class HelloWorldApp{ static void Main(string args) { System.Console.WriteLine("Hello, world!"); }}或者（仅用于Microsoft Windows）
class HelloWorldApp{ static extern MessageBox(string title, string message); public static void Main() { MessageBox(null, "Hello, world!"); }}或者（使用附加的Windows Forms）
using System.Windows.Forms;class HelloWorldApp{ public static void Main() { MessageBox.Show("Hello, world!"); }} IDENTIFICATION DIVISION. PROGRAM-ID. HELLO-WORLD. ENVIRONMENT DIVISION. DATA DIVISION. PROCEDURE DIVISION. DISPLAY "Hello, world!". STOP RUN.;直接輸出"Hello world!" ;或者(format t "Hello world!~%")
@echo Hello, world!
对于MS-DOS 3.0或更低版本：

echo Hello, world!class HELLO_WORLDcreation makefeature make is local io:BASIC_IO do !!io io.put_string("%N Hello, world!") end -- makeend -- class HELLO_WORLD -module(hello). -export(). hello_world() -> io:fwrite("Hello, World!\n").

使用Qt
#include <QApplication>#include <QLabel>int main(int argc, char *argv){ QApplication app(argc, argv); QLabel label("Hello, world!"); label.show(); return app.exec();}C 和 GTK+
#include <gtk/gtk.h>int main(int argc, char * args){ GtkWidget * win, * label; gtk_init(& argc, & args); label = gtk_label_new("Hello, world!"); win = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_container_add(GTK_CONTAINER(win), label); gtk_widget_show_all(); gtk_main(); return 0;}用C++和gtkmm 2
#include <iostream>#include <gtkmm/main.h>#include <gtkmm/button.h>#include <gtkmm/window.h>using namespace std;class HelloWorld : public Gtk::Window {public: HelloWorld(); virtual ~HelloWorld();protected: Gtk::Button m_button; virtual void on_button_clicked();};HelloWorld::HelloWorld() : m_button("Hello, world!"){ set_border_width(10); m_button.signal_clicked().connect(SigC::slot(*this, &HelloWorld::on_button_clicked)); add(m_button); m_button.show();}HelloWorld::~HelloWorld() {}void HelloWorld::on_button_clicked() { cout << "Hello, world!" << endl;}int main（int argc, char *argv）{ Gtk::Main kit(argc, argv); HelloWorld helloworld; Gtk::Main::run(helloworld);}import java.awt.*;import java.awt.event.*;public class HelloFrame extends Frame { HelloFrame(String title) { super(title); } public void paint(Graphics g) { super.paint(g); java.awt.Insets ins = this.getInsets(); g.drawString("Hello, World!", ins.left + 25, ins.top + 25); } public static void main(String args ) { HelloFrame fr = new HelloFrame("Hello"); fr.addWindowListener( new WindowAdapter() { public void windowClosing(WindowEvent e) { System.exit( 0 ); } } ); fr.setResizable(true); fr.setSize(500, 100); fr.setVisible(true); }}Java Applet用于HTML文件。
HTML代码：
<html><head><title>Hello World</title></head><body>HelloWorld Program says:<applet code="HelloWorld.class" width="600" height="100"></applet></body></html>
Java代码：
import java.applet.*;import java.awt.*;public class HelloWorld extends Applet { public void paint(Graphics g) { g.drawString("Hello, world!", 100, 50); }}JavaScript是一种脚本语言。最广泛用于HTML文件中，也可以用在其它宿主环境下，比如Microsoft® Windows® 脚本宿主（WSH）和一些web服务环境。
用于HTML中：
alert("Hello, World!");//或者document.write("Hello, World!");用于WSH中：
WScript.Echo("Hello, World!");PostScript是一种专门用来创建图像的语言，常用于打印机。
