Abstract Data Types
Abstract
This chapter extends the coverage of structured programming to include abstract data types (ADT). It begins by giving the definition of an abstract data type and giving a small example of an ADT that could be used to read, process, and write Netpbm images. The next section introduces an ADT written in C to perform word frequency counts, and shows how performance can be greatly improved by using better algorithms and/or by writing some functions in assembly language. It also shows how a binary tree structure created by C code can be traversed in assembly language. The chapter ends with a ethics module about the Therac-25 cancer treatment device.
