All right, c p 1 dot y, x I've said assign that to the value 2, 2,0. So now c p 1 has inside of it an x and y value.

Where x and y are floats.
我需要很多个引号，好。
-
But here, if I decide I'm going to store things not in x and y, but with some other set of names, for example, I've gotta go back into these pieces of code that use the points, and change them. So I've lost modularity.
除了要改下借口,但是这里，如果我决定，我不把值放在x和y中，而是和其他一些变量名进行绑定,例如这样的话,我就得回到使用这个点的代码，那儿去做更改了。

swap If main wants to give access to swap to x and Y, it just has to tell swap where x and y are.

x and get the values of x and y attached to this thing and return them to me.
和y值然后把它们返回给我，It’s，going，to，go，off,这就是我想要的东西,我想要我的类里面有一些方法。
-
And you can very quickly take this feature to an extreme 10 and start putting X and Y and A and B and 10 and all your variables up top because it would seem to solve all of your problems and stop all of your thinking, but it's generally not a good thing.
