If you scroll back up on the printout or screen here, you'll see that you can actually not only declare function's prototypes, their general structure.

如果我回滚到打印输出或者这个屏幕，你们将看到你们不仅可以声明函数的原型,它们的一般结构。

printf I have my includes, standard IO's; so I can use print F, but then I had this thing called a prototype.

我包含了标准输入输出文件，所以我可以使用，然后我有这个原型。

For some reason, at the top of this file, I've also included what I've called a function prototype.

因为一些原因，在这个文件顶端，我包含了一个函数原型。

Here in functions prototype it just means the address of.

这个函数原型中，它指的意思地址。

I have to change the prototype of this function to say that swap no longer takes an int per se or another int per se, but rather it takes two pointers, two ints, and in fact, it's on the very last page if you're still flipping.

我改变了这个函数的原型,来说明swap不再携带那两个int数本身，而是携带两个指针，两个整型数指针，实际上，它是在最后那页上。

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。
