• Project 5
• Prof. Jerry Breecher
• CSCI 140
• Spring 2005

What You Will Do In This Project

• The purpose of this project is to take the next
  steps in writing a more complex program.
• You are working toward writing a program that can
  take in the following input
• ADQltwsgtstring1ltwsgt.ltwsgtstringN
• Where
• ADQ means Sort in Ascending order, Descending
  order or Quit.
• ltwsgt whitespace space or tab.
• There is a considerable amount of work to do
  here, and so it makes sense to divide this into
  smaller pieces.
• Project 3 Handling arbitrary number of strings.
• Project 4 Parsing a long string looking for
  arbitrary characters.
• Project 5 Putting it all together.

What You Will Do In This Project

• This is the final project in the sequence youve
  been working on. Here you will be able to take
  in a single line containing all the information
  you need to sort strings.
• ADQltwsgtstring1ltwsgt.ltwsgtstringN
• Where
• ADQ means Sort in Ascending order, Descending
• order or Quit.
• ltwsgt whitespace space or tab.
• The general delimiter you were working with in
  the last project is now only a space or tab. You
  no longer need to input that delimiter since you
  know what it is.

What You Will Do In This Project

• Groundrules
• Credit for Projects
• Is based on deliverables.
• You do not need to turn in High Level Code or a
  test plan but you may find the examples later in
  this writeup to be useful.
• You will be expected to do a Show and Tell one
  week after the project is assigned. See the
  evaluation sheet.
• You will also be expected to turn in your
  assignment, placing it in the CS140 submissions
  directory. To do this, name your completed code
  as proj5.s, and then from the directory in which
  the code currently resides, type the following
• jbreecher/turnin.pl 140 proj5.s

A Test Plan

• Here are some possible inputs that you can check
  for. I have attempted to give you some
  interesting and unusual conditions. As usual,
  there are many other possible test cases.

Project 5 Evaluation Sheet

• Name____________________________________________
  _____________
•  
• Is there a complete set of test cases?
•  
•  
• Does the MIPS program work as expected on test
  cases?
•  
•  
• Does the code handle consecutive white-space
  characters?
•  
•  
• Are there other special features associated with
  this program?
•  
•  
• Is the code readable and well commented?
•  
•  
• Is the code organized as a set of functions
  rather than as one big chunk of main code?
