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。

It's a little redundant, admittedly, but I include not the same function, but just its prototype, as I say in the comment here.

它确实是有点长的，但是我包含的不是同一个函数，而只是一个原型，就像我这里的注释所说的。

The only thing that you have to put in the function prototype, ; again, is three things; one, the name of the function; the return value; and its arguments.

你唯一要加入到函数原型中的东西，是有三个东西，一，函数的名字;,返回值，和它的参数。

What's the prototype of a function?

什么是一个函数的原型呢？

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。
