One is based on Scrabble, the board game where players try to form words from letters with different point values.

So both of these stories involve floating point values, but only in this case am I actually allocating memory.

所以这两个故事都涉及到浮点类型，但是只有那样我们才能真正地分配到内存。

Given the abstraction, the notion of a point as an instance with some values, I can now start building segments.

真的很有帮助，基于这个抽象,点的概念也就是一个，有一些值的实例。

And I can fix this just by changing one of those values to a floating point.

所以我可以通过改变其中一个,整型数为浮点数。

Let's let p be Cartesian point, and we'll give it a couple of values. OK?

然后我们给它赋值，好不好？,发生了什么？

Let me give you, I'm going to create, q a polar point, I'm going to call it q, and we'll give it some random values.

让我给大家讲解下，我要去创建，一个极坐标点，然后我会去命名它为，然后我给它赋一些随机的值，好，现在我想知道。

But if you've looked at more recent or if you've looked at friends who relatively recently signed ID up for Facebook, their profile IDs which you sometimes see in the URL are actually pretty long and that's because I believe at some point they did transition longlong to 64-bit values which tend to be called long longs.

但是如果你看过最近的【听不见】,如果你访问了最近在Facebook上留言的朋友,你会发现，可以从URL上看到他们的配置文件,很长很长，那是因为,可能在某个时间点，他们已经过渡到,64比特了，也就是所谓的。

And that's a wonderful thing to have because it gives you that modularity, that encapsulation that basically says, when I create a point, the only way I can get at the values, is by using one of the defined methods, in this case it could be Cartesian, Cartesian and get all the pieces of that.

这是很棒的一件事情,因为它让你有了，模块性以及封装性，这基本上也就是说，当我创建了一个点，我能够得到它的值的唯一的方式，就是用一个定义好的方法，在这个例子中也就是。
