在不到10行简单代码中，你能做的最酷的事情是什么?帮我启发初学者吧!

我正在寻找最酷的事情，你可以在几行简单的代码。我相信你可以用Haskell用15行写一个Mandelbrot集，但是很难理解。

我的目标是启发学生编程很酷。

我们知道编程很酷，因为你可以创造任何你想象到的东西——它是最终的创意出口。我想激励这些初学者，让他们尽可能多地克服早期学习的困难。

Now, my reasons are selfish. I'm teaching an Intro to Computing course to a group of 60 half-engineering, half business majors; all freshmen. They are the students who came from underprivileged High schools. From my past experience, the group is generally split as follows: a few rock-stars, some who try very hard and kind of get it, the few who try very hard and barely get it, and the few who don't care. I want to reach as many of these groups as effectively as I can. Here's an example of how I'd use a computer program to teach:

Here's an example of what I'm looking for: a 1-line VBS script to get your computer to talk to you: CreateObject("sapi.spvoice").Speak InputBox("Enter your text","Talk it") I could use this to demonstrate order of operations. I'd show the code, let them play with it, then explain that There's a lot going on in that line, but the computer can make sense of it, because it knows the rules. Then I'd show them something like this: 4(5*5) / 10 + 9(.25 + .75) And you can see that first I need to do is (5*5). Then I can multiply for 4. And now I've created the Object. Dividing by 10 is the same as calling Speak - I can't Speak before I have an object, and I can't divide before I have 100. Then on the other side I first create an InputBox with some instructions for how to display it. When I hit enter on the input box it evaluates or "returns" whatever I entered. (Hint: 'oooooo' makes a funny sound) So when I say Speak, the right side is what to Speak. And I get that from the InputBox. So when you do several things on a line, like: x = 14 + y; You need to be aware of the order of things. First we add 14 and y. Then we put the result (what it evaluates to, or returns) into x.

这就是我的目标，有一堆很酷的例子来演示，并在他们玩得开心的时候教他们。我在我室友身上尝试了这个例子，虽然我可能不会把它作为第一课，但她喜欢它，并学到了一些东西。

一些很酷的数学程序，可以做出漂亮的图形或容易理解的形状，这是很好的想法，我将研究这些。这里有一些复杂的actionscript示例，但这有点太高级了，我不能教flash。你还有什么其他的想法吗?

Squeak是一个激发灵感的好工具

有点离题了，但你可以看看这个推文编码，它使用了不到140个字符的as3代码:

在您的地址栏(在您的浏览器中)输入此代码并按Enter。然后你就可以编辑网页的所有内容了!

javascript:document.body.contentEditable='true'; document.designMode='on'; void 0

这是我知道的最酷的“一句俏皮话”=)

我记得我发现简单的循环很神奇。每次我学习一门新语言，我通常会把这样的东西放在一起:

<?php
$numberOfBottles = 99;
print("<h1>$numberOfBottles Bottles of Beer on the Wall</h1>");
print("$numberOfBottles bottles of beer on the wall,<br />");
print("$numberOfBottles bottles of beer!<br />");
print("Take one down, pass it around,<br />");
for($numberOfBottles--; $numberOfBottles>1; $numberOfBottles--)
{
    print("$numberOfBottles bottles of beer on the wall!<br />");
    print("<br />");
    print("$numberOfBottles  bottles of beer on the wall,<br />");
    print("$numberOfBottles  bottles of beer!<br />");
    print("Take one down, pass it around,<br />");
}
print("One last bottle of beer on the wall!");
?>

也许一些while或foreach循环的变化也会很容易。
