CSC 290A, Spring 2009: Homework

The following page lists the homework, written or programming assignments, for the Spring 2009 class. The homework is listed by due-date order : newest should be on top.


  • Submit your example and solution code through the CS department wiki by creating a new page or a set of new pages. Make them changable by only you and viewable by you, KonstantinosMenychtas, and ChenDing.
  • We have collected a set of easy to follow hints/guidelines on the Wiki-related hints page, including page creation, basic formatting, and access control.

Homework 1: Extensible Design NEW

A common software problem is to develop a set of tools operating on a collection of data. The goal of extensible design is to structure the system so that new tools and new data types can be added without changing the code for existing tools and data types.

In this assignment, you are asked to come up with an example programming problem and demonstrate an extensible design on the example problem. The specific requirements are

  • the problem should involve data with recursive data types
  • the existing solution should have at least one data type and one tool
  • the extension should include at least one new data type and one new tool

The design will be evaluated not only in terms of correctness but also the brevity and clarity of your program. You are encouraged to use this exercise as a way to evaluate the object-oriented features of your favorite programming language and compare it with newer alternatives especially the one we discussed in class, Ruby.

Homework 1 is due midnight, Sunday Feb. 1st.
