But what looks like this orange block as of now in Scratch, add orange to your so called inventory, well, it's gonna take at least two lines of code in C to actually create the inventory array with this first line and then put something like the word orange inside of it.

就好比Scratch里面橘色的这一块，把“桔子“加到所谓的“清单“里面去,在C语言中至少需要两行代码来实现,第一行代码创建一个货单数组,第二行就需要把“桔子“放进去。

We can put a list in the list again, as we've seen before. So let's put the list containing the string a, and I'll print out so now we see something pretty interesting about a list, that we can mix up all sorts of things in it, and that's OK.

数组放到数组中去，让我们把这个包含,字符串a的数组放进去,然后再显示，我们看到了一些,挺有趣的事情：我们可以把各种,各类的东西混合着放进去，没问题。
