Graphic displays of data structures on the IBM PC

Published: 01 February 1986 Publication History

Abstract

Immediately or soon after an introductory course in programming, traditional computer science education usually includes a course on data structures. Such courses, however, have suffered from a lack of non-textual materials for classroom and non-classroom use. Consequently, it is difficult for students to comprehend the abstractions involved in implementing and applying fundamental data structures without laboriously employing printed materials.
The work discussed herein addresses the problem by developing software for the IBM PC that will allow data structure users to view graphically the effects of primitive operations and application programs on basic data structures. Several such structures and applications are examined and plans for a program interface are discussed.

This paper describes a set of primitive graphical display operations that can be added to Pascal program code to show dynamically how certain data structures change as the program runs. The authors have implemented routines that can be used to display arrays, stacks, queues, binary trees, and linked lists. These tools, the authors argue, can be used to help students understand the dynamic behavior of these data structures. They might also be used by applications programmers to help them debug programs that use dynamic data structures. The authors have implemented the graphical display operations in a way that lets a program create a file which can be “played back” to show how its data structures changed as the program ran. They propose, but apparently have not implemented, a system that will show the behavior of dynamic data structures in real time, making it possible for the user to interact with the program and the data structures as they evolve. The paper contains no information on how the routines were implemented, but it contains examples of how they can be used to display the performance of a bubble sort.
