You can stack these things in C. So if you want to do if - and then rather -- let me tweak this just so simplify -- if you want to stack these things and do this in one case or that in the other, can you stack them like this?

你们才可以在C语言中使用这些东西，所以如果你想做,-让我把这个弄得更简单点-,如果你想把这些代码堆集在一起，在一个情况中,或在另一个情况中处理，你能够像这样把他们集在一起吗？

And I don't quite remember from reading or from class how big these things are, well, it turns out -- and this is sometimes useful, later on more likely than now -- but C has a size of operator that takes an argument in parenthesis and it will tell you how much space is used to store that particular data type.

我不太记得类中的这些类型,是多大的，嗯，结果是--这个在以后比现在，可能是更有用的--不过C语言中有个sizeof的操作符,其中括号里有一个参数,它会告诉我们，要存储一个类型的数据,需要占用多大空间。
