到现在为止，我还没有写任何的,它们自己携带参数的程序，但是,我完全可以这样做。

X So here I'm declaring another variable called X, and this is totally legitimate because I already know that if I'm implementing a function like swap or increment, I can absolutely take input.

这里我声明另一个变量，这个完全是合法的因为我已经知道,如果我执行一个像swap，或，increment的函数，我完全可以携带输入。

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。
