So, if we think about the second case here where we have c n minus, now we're talking about a molecule with a net charge of negative 1.
那么，如果我们考虑的是第二个例子,也就是氰离子，那么现在我们讨论的是一个净电荷量为负一的分子。

So, let's try another example here, and let's try a case now where instead of dealing with a neutral molecule we have an ion, so we have c n minus.
那么，让我们来试一下另外一个例子，这次不是一个中性原子,而是一个离子，氰离子。

I can't give it what it wants," know that when you're writing code and the problems that will remind of this, if you absolutely have to kill your program, you don't have to close the window, CTRL+C reboot crazy stuff like that, generally you can hit CTRL+C and it will just abort the program right where it is, in case you ever get trapped in some awkward situation.
我不能给它所要的“,当你在写代码时，程序将,提醒这个问题，如果你不得不,关闭这个程序，你不需要关闭这个窗口，重启像那样的疯狂举动，通常你可以敲,它将会在这个地方终止那个程序，假使你陷入了尴尬的处境。

In that case, y will be -gt^/2+c+bt.
在这个情况下y=-gt^/2+c+bt

In this case we have a double bond between a and b, and in this case we have it between b and c.
在这种情况下，我们在，A，与，B，之间有一个双键，而在这种情况下，双键在，B，与，C，之间。

So with the fact that I'm now just back at my prompt is a good thing so now GCC hello c if I type this command GCC hello.c, this is gonna run this program that Apple wrote in this case GCC or someone else wrote called GCC.
也就是说我们现在安全返回,说明一切正常,现在我输入这条命令：,这代表运行hello，c这个程序,是由“Apple“或其他人编写的，名为。

So this code is identical functionally nonswitch c to the last implementation we saw, nonswitch.c, but I'm just ever-more emphatically saying, "In case 1," that is when n equals 1 -- or when case 2 applies -- when n equals 2 or when n equals 3 do what?
所以这些代码到最后的实现上，功能是,完全相同的，但是我想要再次强调一下，“在case，1“，那是当n等于1时1,或者当case，2适用-,当n等于2或者当n等于3，它将做什么？

So, let's just arbitrarily put it between these two in this case here, but actually there's no reason we couldn't also put it between oxygen b and c, so I'm going to draw another structure where we have it here.
那么，让我们任意地将它们放在这两个之间，但实际上我们没有理由,不能把它们放在氧原子，B，与，C，之间，因此我将把另外一个结构画在这里。
