So the enrollment numbers are in and we thought we would share some statistics, as we like to do in this course; being computer scientists, we tend to gather lots of data.
登记加入我们的人数在这里,并且我们觉得我们能分享一些统计资料,我们在这次课程中也喜欢这么做,作为计算机科学家,我们要收集很多数据。
We're talking about like, if you didn't, even if you had all your data on your computer backed up on hard drive,
如果你没有将你电脑里的数据备份到硬盘里,
And the second thing we're going to need, is we're going to need a way to give instructions to the computer to manipulate that data.
我们需要的第二件事情是,我们需要一种,能给予计算机指令,以操作数据的方式。
It's the various programs you run on your computer along with the various data files that you have saved on your hard drive,and so forth.
是你自身这个电脑中运行的各种程序,硬盘存有的各种数据和文件,类似种种。
- But the computer-- but a lot of data about all the students on campus were-- -- was collected--were collected and people were then randomly paired up and sent to the dance.

But one of the teaching fellas also passed long to us recently, a little real world example of what happens when you're not mindful of various data types and you're not mindful of the imprecision that's inherent in representing data in a computer, at least using a language like C and low level primitives like floats and even doubles.
最近有个助教告诉我们,一个现实世界中的例子,当你不注意各种各样的数据类型,也不注意在计算机中表示数据时,其内在的不精确性,至少在用像C语言,和float甚至double型数据时,那将会发生什么?
I've added the ability to have more complex data structures here. But I dropped a hint in the first lecture about what you could computer with things. In fact if you think for a second about that list, you could ask what can I compute with just that set of constructs?
我添加了使用更复杂的数据结构的能力,但是我在第一节课给大家了了一个,关于你可以用什么来做计算的暗示,实际上如果你思考,这个列表一会儿的话,你会问我可以用?
