And even though the syntax, the characters you are about to see on the screen and in programs today onward is a little more arcane, it's a little uglier looking, you've got semicolons and parentheses and fairly arcane syntax, realize that at the end of the day these are just arbitrary human conventions, the ideas are identical to this thing here.

可能你在屏幕上，编程中见识到的,语法，字符看起来非常晦涩难懂,甚至可以说是丑陋，像什么分号啊,括号啊等等，还有一些难七八糟的语法，但是到了最后，你会发现,这些都不过是一些人为约定而已，而蕴含在里面的编程思想跟这个例子并无二致。

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。
