stdio h This file here is called standard I/O or stdio.h and this is just another text file someone else wrote many years ago and by using that line of code there, I'm telling the computer, give me acces to this code that this other person wrote that's in that file.

在这里的头文件称为标准输入输出文件或,这是由某位前人编写的文本文件,我们只需要刚才所述的一行代码，就能告诉电脑，让我连接到,这个前人在那个文件中写的代码。

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。

Why is this much nice? Well, that's a handy piece of code. Because imagine I've got that now, and I can now store that away in some file name, input dot p y, and import into every one of my procedure functions, pardon me, my files of procedures, because it's a standard way of now giving me the input.

为什么这样很好呢？,这是一段很好用的代码,因为想象下如果我有了这段代码,我能把它用某个文件名保存起来,后缀是。py，导入到所有的处理函数中,抱歉，我的处理文件,因为这是一个标准的输入方法。

cs50 h It's not called standard io.h, it's called cs50.h. That's where the code we wrote for you will live and then we'll see how to do this in examples today onward but we wrote for you some tools, some functions that calls GetChar for get a character.

当然不是标准输入输出库了，而是叫做,这里面有一些我们写的代码,等一下我会举几个例子,我们写了一些函数,比如GetChar，意思是得到一个变量。
