‘Hello world’ in 20+1 different programming languages

Hello! Since it is my first blog post I decided to write a ‘hello world’ post with examples from different programming languages.

A hello world program is used to give the reader a quick overview of the programming language syntax and also get the code for the bare minimum program to run.

Le’ts not waste another minute and get to it.

  1. PHP
    <?php echo "hello world!";?>
  2. Javascript
    alert("hello world!");
  3. Python
    print("hello world")
  4. C
    int main(void)
    puts("Hello, world!");
  5. C++
    #include <iostream.h>
        cout << "Hello World!" << endl;
        return 0;
  6. C#
    using System;
    class Program
        public static void Main(string[] args)
            Console.WriteLine("Hello, world!");
  7. Objective C
    int main(void)
    &nbsp; &nbsp; NSLog(@"Hello, world!");
    &nbsp; &nbsp; return 0;
  8. HTML
    Hello World!
  9. Matlab
    disp('Hello, world!')
  10. Java
    class HelloWorld {
      static public void main( String args[] ) {
        System.out.println( "Hello World!" );
  11. MS DOS
    ECHO Hello World!
  12. Linux Bash
    echo "Hello World!";
  13. Node.js
    var sys = require('sys');
    sys.puts('Hello World');
  14. Ruby
    puts "Hello World!"
  15. BASIC
    10 PRINT "Hello World!"
  16. Visual Basic 6
    Private Sub Form_Load()
    Print "Hello World"
    End Sub
  17. Visual Basic .NET
    Imports System.Console
    Class HelloWorld
        Public Shared Sub Main()
            WriteLine("Hello, world!")
        End Sub
    End Class
  18. Pascal
    program HelloWorld(output);
      WriteLn('Hello World!');
  19. ASP.NET
    <%= "Hello World!" %>
  20. Fortran 77
    PRINT*, 'Hello World!'
  21. Arduino
    void setup()
      Serial.println("Hello, world!");
    void loop()


When I started writing this post I was sure I would write each hello world on my own. But as the list was growing I got a bit tired and googled some of the programs. Doing that I stumpled upon a website with 533 ‘hello world’ programs http://helloworldcollection.de/
