At the site of the crash, investigators spent hours combing through the mangled remains of the aircraft to find the plane's black box, flight-data recorder.

A low-level language, we used to call this assembly programming, you're down at the level of, your primitives are literally moving pieces of data from one location of memory to another, through a very simple operation.
一个低级的语言,我们曾经将其称为假设编程,你们只是处于用基本要素,把一些数据碎片,从记忆存储器的一个地方,通过简单的操作来转到另外一个地方。
I, somehow if, I want to walk through some sequence of data structures, gathering up or doing the same thing, adding ages in until I get a total age and then divide by the number faculty.
我想,以某种方法,来遍历,一些数据结构,把它们相同的属性加到一起,就是一直的把年龄加到一起一直到,得到了一个年龄总数,然后除以员工的数目。
Now I'm putting count in double quotes, not to make it a string, but to say, this is count generically. It could be counting one by one through the integers, it could also be taking a collection of data and going through them one by one. It could be doing counting in some other mechanism.
现在我把count用双引号标起来,不是说把它命名为一个字符串,而是说,这是一个通用的计数器,它可能是每一次减1的整数,也可能是拿一个集合的数据然后,一个一个的访问它们,也可能是以某种机制来计数。
That is basically saying, given some collection of data, I want to have again a looping mechanism, where now my process is, walk through this, the collection one element at a time. And for that, we have a particular construct, called a FOR loop.
现在我的过程就是,通过一个个访问这个集合中,的元素的方式,来遍历这个集合,为了达到这个目的,我们有一个特定的结构,成为FOR循环。
