I get to the end of the loop, and I actually do a little bit of wasted motion there. And the little bit of wasted motion is, I take the value at i, store it away temporarily, take the value where min index is pointing to, put it back in there, and then swap it around.

X That's just the special symbol in C that says don't pass X, that is don't pass a copy of X. Rather figure out where x is in memory, where he is in that frame and provide swap the numeric address in RAM of that value so that swap can go do anything it wants at that address.

Indeed, swap in your printout there is just defined as now taking *a and *b and then it also uses the * later, but we'll come back to what the different uses of the * means, but for now I claim conceptually it just means swap has access to the locations of its parameters.

I'm reminded of the confirmation screen here and that's not too bad, then we put in the card and we click confirm and then finally we see the swap Then finally literally nine steps later the ticket comes out of the machine and then, frankly, had to go through the process of where to put the ticket in the machines.
这里出现了确认画面,那还不是太坏，然后我们把卡插进去,点击确认，然后我们看到了那个,函数。，swap，function。,【笑声】然后最终经过9个步骤,票从机器中出来了，然后，需要找出从哪里,把票放到机器中去。
