All right? Now, I'll say L 2 equals L 1.

好，然后我新建个L2数组和L1相等。

lstd So this is pretty-- similarly might we say this dash L STD for standard, for Standard I/O.

同样也可以是,即标准输入输出库。

So, if we think of just an example, 2 we could say that 4 l equals 2, what would be our lowest value of m sub l?

举个例子，如果我们说l等于，那m小标l，最小值是多少？

Now I'll print L 2. Kind of what you'd guess, but here's the interesting question: if I say L 1 is assigned 0, L 1 sub is assigned 4, I'll print L 1.

然后我将显示下L2的内容，你，们猜猜这个有趣的问题：,如果我将L1赋值为4的话，再去显示下L1，会怎么样呢？

You might wanna say dash L math but it turns out /lm it's so common that people just say dash LM.

你们可能会说，/lmath，其实可以简化,因为使用太广泛了，一般都简化为。

So if we say that l is just talking about our kinetic energy part, our rotational kinetic energy, and we know that electrons have potential energy, then it makes sense that l, in fact, can never go higher than n.

如果我们说，l仅仅是,描述动能项，我们的旋转动能，我们知道，电子有势能，所以可以理解，l不能比n高。

Whereas CS50 is not nearly as popular a library in the world, -lcs50 and so you'll have to explicitly say dash L CS50.

但是CS50库就没那么出名了，所以你必须在后面清清楚楚地添上。

ml=-2 So let's say we have n equals 4, and n sub l equalling negative 2.

这里n等于。

long l So let me try this, long l, and then let me do a little Copy Paste here and say a long is actually the size of l. So let me quit that program; recompile.

让我们来试一下，然后我在这里复制粘贴一下,这里long的大小实际上是l的大小，所以让我退出,那个程序，重新编译。
