And don't wear it out.
You say Hello, of course
Here's a quick look at how different programming languages handle that simple task.
Visual Basic:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
MsgBox("Hello World!")
End Sub
C#:
public class Hello1
{
public static void Main()
{
MessageBox.Show("Hello World!");
}
}
C++:
#include <iostream>
using namespace std;
int main ()
{
std::cout<<"Hello World!";
return 0;
}
HTML
<html>
<body>
Hello World!
</body>
</html>
JavaScript
alert("Hello World!");
PHP
<?php
echo "Hello World!";
?>
PHP
class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
Pascal
program HelloWorld(output);
begin
WriteLn('Hello World!'
;
end.
Python
print("Hello World")
Ruby
puts "Hello World!"
Perl
print "Hello World!\n";
If you can think of any other good programming languages to include, just say so.

Well the latest official version of python doesn't requite the parenthesis, and since the people using "Hello World!" are probably new to the language, they're probably using that newest version.
Although I see that you're defiantly right about C++, I'll have to change that in a little bit

C++ One does not require the name space std when calling cout directly using std::

Why are you using the namespace std and still using an unary scope resolution operator to retrieve the cout-command from the library?
Here's a fixed version:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello World!" << endl;
return 0;
}
And here you have my sexy 16-bit ASM variant:
; Hello World!
; Microsoft Assembly Syntax
; To assemble, use DEBUG.EXE.
; Assemble at 0100h.
; Written by xNCK.
; Register DX will be filled with the hex value of its ASCII value (x = 120 = 0x7
; int 21h will output register DX to the screen.
; int 20h will terminate the program.
mov ah, 02
mov dx, 0048

mov dx, 65

mov dx, 6C
