Expect the address of an int but here in the context of the function itself inside the curly braces, it means go to that address.
一个整型数的地址,但是在函数,大括号中的环境中,意思是定位到那个地址。
And then what I get to do inside the curly braces is literally line by line enumerate the cases that I want to apply to the following code.
然后我们在花括号中要做的是,逐行地列举接下来我想要,应用的代码。
So if we want to put that in chemical terms, we want to make sure we put these in brackets here, and remember, this is the resonance arrow, it's not a reaction arrow, it's a resonance arrow, so make sure you mark it up correctly like that.
那么如果我们把它类比到化学中来,我们要确保它们都放在括号里,而且要记住,这是一个表示共振态的箭头,而不是表示化学反应的,它是一个表示共振态的箭头,因此请务必像这样正确地标记它。
But the moment swap returns, the moment we hit this bottom most curly brace, what conceptually happens in memory?
但是swap返回时,当我们抵达花括号底端是,在内存中发生了什么?
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。
As an aside, if you ever just have one line of code that you want to execute, one puzzle piece in Scratch terminology, ; you actually don't need the curly braces; you only need the curly braces if you have two or more lines of code that you want to execute if that condition is true.
此外,如果你只有一行代码,需要执行,在Scratch,术语中叫做,一句代码,你就不需要使用花括号了;,如果那个条件成立,你有两行或更多行的代码时需要执行时,你就需要花括号。
