Property List Project, Part 2

Introduction

This document describes "Homework 5b," The second part of the Property List project. The due date is Week 8 (10/29; 10/25).

For this assignment, You will add two new commands to the program you wrote for Homework 5a: In addition to "exit" and a property name, change your program so that it recognizes the commands, "getval" and "show ." The getval command is used to display the value part of a property list entry, and show displays all the entries in the property list.

Your application program must use the three functions whose prototypes are in ~vickery/CS-200/Homework_5b/plist.h: insert(), getValue(), and showList(). Note that the prototype for insert() for this assignment is slightly different from the prototypes used for Homework_5a. You must use the new plist.h for this assignment, so you will have to change the code you wrote to call insert() before.

You are also to implement the three functions listed above. For your convenience in developing this assignment, there is a compiled version of the solution in ~vickery/CS-200/Homework_5b/plist.o. Your application program must work with this version of plist.o as well as with the one that you write yourself. Again, the plist.o file for this assignment is different from the one for Homework_5a, so be sure to use the correct one.

Requirements:

The property list must be implemented as a linked list, not as an array.
The property list must be sorted by property name at all times. If the same property name occurs twice (or more) the sequence of those entries does not matter. [Optional: sort entries with the same name according to their types.]
Every name/type combination in the list must be unique.
You must use the file "plist.h" that I supplied in both your application program and in your implementation of the Property List package.
Your main program must work properly when linked with the plist.o that I supplied, as well as with your own.
You must use a Makefile that will build your program. You may use the one in ~vickery/CS-200/Homework_5b if you wish, or you may write your own, or you may modify the one that I supplied. When you submit the assignment, provide only your own source files. Do not send any binary files or copies of my plist.h or Makefile. (Of course, if your Makefile is different from mine, send yours.)

Sample Output:

Your output does not have to look exactly like this, but you may use it as a model.
