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.

Clearly I was using Alerts/Messageboxes for languages that supported them, such as C++ and JavaScript, instead of just cout or document.write.
And you don't actually need parenthesis when using print in python

'Kay, but the parenthesis used in python are supported in most version of python, so should be used as default, and the C++ MessageBox only works in WinAPI, and is actually not raw basic C++. :y: , the javascript however, is a valid alert.

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

You should use parenthesis.. Its easier to read, and its a good habbit, for when you do c# and sh1t.

Um, in the newest version of Python (3.2), you need parenthesis. Print is no longer a statement, it is now a function.

print "Hello World!" works for me, just downloaded 3.2 from the website.
Anyways, don't even know why I'm arguing about this; C++ and Python scripts changed by popular demand

It's probably because 2.x is set as default.
This is what will happen in 3.2
>>> print "Hello World!"
File "<stdin>", line 1
print "Hello World!"
