It allows for this map between a symbol, say a spoken word, and any sort of thought we want to use.

语言允许在符号,比如说出的一个词,与我们想要使用的任何想法之间,存在着这种映射关系

So this is the same definition we saw last time, just being a little bit more nerdy and putting in some notation.

这个定义和我们上次讲的是一致的,只不过使用了些符号使它变得有点枯燥

And I want to describe both the syntax, what we're doing, and then the semantics of how do we use it and what does that mean.

现在我想解释一下语法，我们在做什么,还有我们使用时的符号,以及意义。

That's the crucial thing: if they're not willing, the use of the sign doesn't work, which confirms the idea that nothing can be changed simply by individual agency in and of itself.

这很关键：,如果他们自己不愿意使用，符号就没有意义，这也就应证了我们的观点,没有人能单独改变一个群体符号的使用方式。

Now, we're using the equal equals operator and this conceptually is correct.

现在，我们使用==符号,这是正确的。

I think I mentioned to you that the Greeks improved upon it and made it a true alphabet by taking some signs that they didn't need for their own language by turning them into vowel sounds.

我想我向你们提到过希腊人将这种字母表改良,并使其成为真正的字母表,他们把一些并不需要的符号,变成元音使用

Convention, OK, this negative sign is just a pure convention. You just got to use it all the time. If you use an old textbook, written when I was taking thermodynamics, they have the opposite convention, and it's very confusing. But now we've all agreed on this convention, and work is going to be with the negative sign here.

系统对外界做功的符号为负,这就是我们,在本课中的规定，纯粹出于统一符号的需要，有些教科书中，可能会使用相反的符号规定,注意不要混淆了，这门课上,我们将一直使用。

Well, I use the * notation.

嗯，我使用*符号。

Well, simply with the * notation at least on the way in when you declare the function called swap, you simply say this is not going to take an int and another int because that's useless.

好的，简单说，当你声明一个函数调用swap函数时,使用*符号，你可以简单说，这不能使用一个int数和另外一个int数,因为那是无效的。

It may mean something different and this is sort of just stupid re-use of syntax although frankly it wouldn't really be much fun to have yet a symbol so they went with the same symbol which is pretty reasonable in the context *a of a function prototype this just means *a expect A to be the address of an int and expect B to be the address of an int.

这里的意思有点不同,这是为了重使用的目的,虽然这个符号没有什么意义,所以在函数原型中，他们就使用了相同的符号,这只是表示，期望,是一个int型的地址,期望b是一个int型的地址。
