Project #4
Due Date: start of class, Monday, April 9, 2001
In this project you will explore stacks and expression parsing. The
project depends mostly on Chapters 6.1-6.5 and 7, but uses the linked-list
material that you're already familiar with.
Part I.
Program 7.3 shows the specification of a generic package for LIFO stacks.
Your task in this part is to change the private part of this package, and
implement the body, such that a stack is represented as a linked list,
not an array. Needless to say, you must also develop a test program that
ensures that all the package operations behave properly.
Part II.
Program 7.16 (p. 305) is a bottom-up expression-parser function that converts
an arithmetic expression into its RPN form. It does not handle parentheses,
though. Your task in this part is to modify the program so parentheses
are treated properly. Provide an interactive main program that prompts
the user for an input expression, then produces and displays the corresponding
RPN.
What to submit:
-
By now, you should be familiar with the various kinds of project elements,
documents, etc. Submit those elements that are appropriate for this project.
