What lambda that does, it creates on the fly a function, as the program runs. That I can then pass around.

这里的入是在函数运行的时候，由一个函数创建的，然后我会传递这个值。

By putting it in a function bug if I find a bug and I change my program I can just run the function again.

把我输入的值放到一个函数里,如果以后我在程序中发现了一个,并对程序进行更改的话，我可以直接。

And henceforth I'm gonna start calling these tools, these monickers that I can use as building blocks in my own program, it's gonna be called a function as we'll see.

从此以后，我将在我的程序里把这些工具，称为我们可以用来写代码的组件,在我自己的程序中，我们将了解到它被叫做为一个函数。

I certainly don't want to assume they're always going to type a three-letter or a four-letter or a two-letter word I want some dynamism but that's fine because get string can get a string of any length, I can then use the string length function to just ask while the program is running how big is the string that I was handed?

当然我不能假设他总是,输入3个字符或4个字符,或2个字符的单词，我想要动态地分配,因为GetString可以获得任意长度的字符串，然后我可以使用strlen函数,来得到那个我传递的字符串,有多长？
