I want the function, which is a little tool, a line of code I can include in my own programs and generally those tools live in sections two or three of the manual.
我想要一个函数,那是一个小工具,在我程序中可以包含的一行代码,通常这些工具在手册的第二节,或第三节。
But there's a key line of code that I lost over a moment ago and that was this one here.
但是我刚才漏了一行关键的代码,就是这里的这一行。
Right. So similarly, if you've got one line of code with a semicolon at the end saying, this is the end of the statement, it doesn't really make sense to continue that conversation to try to continue conceptually that puzzle piece with curly braces.
对的,类似的,如果你得到了一行代码,后面有一个分号,标志语句的结尾,这就没有意义来继续,那个会话来尝试对那段代码,使用花括号。
So I actually don't need the curly braces because I only have a single line of code.
所以我实际上不需要那个花括号,因为我只有一行代码。
So, I'm getting a string and so what really am I doing in this line of code?
那么,我得到一个字符串,这行代码实际上是干什么的呢?
You can imagine having many lines of code where all of a sudden your closed quote is on the next line all the way on the left.
你可以想象一下,这有很多行代码,突然一个后引号,移到下一行最左边。
temp = *a This line of code here, temp gets *a.
这一行代码。
So really, the rule of thumb if you think back to Scratch is -- that any time you write a statement -- -- something that does something in one line of code -- you generally need the semicolon there.
实际上,根据经验,你们回忆一下在Scratch中,任何时候你们写一条语句-,处理一些操作的一行代码-,你们通常需要在那里加个分号。
In temp. So that means at the end of that first line of code just as before the value of 1 ends A up in a variable called temp because we said go to A and I look around, oh, there's A, what's there?
在temp中,在第一行代码的末尾,值1最终到了叫做temp的变量中,因为我们指明了定位到,并且四处查看,哦,这里是A,里面是什么?
include stdio h The next line of code says include standard io.h which just as a little sanity check contains among other things, printf.
接着的一行代码写着,这个库文件包含一些我们常用的函数,譬如,printf函数。
The standard library, that first line of code, it's not strictly necessary but any time you use a function, a tool that someone else wrote that lives in that so called library, you do need that include line as we'll see.
标准库函数--第一行代码,严格来说,不是每次都要写的,但是一旦你调用某个别人写,的函数,而这个函数又恰巧位于标准库里面,你就要像我们看到的这样,把它include进去。
You can certainly hit Enter but as we saw-- seen that very quickly makes a mess of your code and such and so backslash N is new line.
你也可以敲回车键-,但是会让你的代码看起来乱七八糟,反斜杠n就是换行符。
