这个任务的目的是更熟悉位级表示和操作。你会通过解决一系列的编程难题来解决这个问题。“很多这样的谜题都是人为的，但你会发现的。你自己想的更多的是通过你的方式通过他们，你将学到很多关于如何计算机表示整型数据。(The purpose of this assignment is to become more familiar with bit-level representations and manipulations. You'll do this by solving a series of programming ``puzzles.'' Many of these puzzles are quite artificial, but you'll find yourself thinking much more about bits in working your way through them and you will learn a lot about how computers represent integer data.)
