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?

我认为任何可以做一些有用的事情的shell脚本都是向人们展示编程力量的好方法。在我看来，能够在一个小脚本上花费10-20分钟来自动化另一项任务并节省无数小时是非常令人印象深刻的。

例如，我曾经写过一个简单的Perl脚本，将一个目录中的mp3文件转换为另一种格式，然后将它们刻录到cd上。你用mp3目录的路径调用这个脚本，它就刻录了cd。至少当时我印象深刻。

就像……

10 rem twelve times table

20 For x = 1 to 12

30  For y = 1 to 12

40     print using"####";x*y;

50  next y

60  print 

70 next x

80 end

这是一个Python telnet服务器，它将询问用户名并向他们打招呼。这看起来很酷，因为您正在通过网络从不同的计算机与您的程序通信。

from socket import *
s=socket(AF_INET, SOCK_STREAM)
s.bind(("", 3333))
s.listen(5)
while 1:
   (c, a) = s.accept()
   c.send("What is your name? ")
   name = c.recv(100)
   c.send("Hello "+name)
   c.close()

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。

大多数答案都使用某种API，这在某种程度上打破了10行代码的要求。每个API调用可能包含数百行代码。最初的问题说要使用“简单代码”。这对我来说意味着没有API调用。仅仅使用“简单代码”的定义，我们能得出什么样的答案呢?

Back in computer class in high school, myself and a couple of friends taught the class how to program with Delphi. The class was mostly focused on programming with Pascal, so Delphi was a good next step. We demonstrated the event driven nature of Delphi and its RAD capabilities. At the end of the lesson we showed the class a sample application and asked them to reproduce it. The application asked "Are you drunk?" with two buttons Yes and No. ...I think you know what is coming next...the No button changed locations on mouse over and was almost impossible to click.

学生和老师都从中得到了很大的乐趣。

该程序只需要几行用户编写的代码和一个简单的方程来计算按钮的移动位置。我想其他学生都没发现，但也有几个很接近。
