Introduction to Computer Science II http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12 Computer Science 12 -- Introduction to Computer Science II en-us Update to the Final Project page http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-12-21-project-final.html 2007-Dec-13: The posting for the Final Project has been updated. There are a couple more test inputs, a new BitSequence class for you to use, and a pre-compiled Huffman classes to help you do some incremental development. Optional Final Project for 2007-Dec-21 http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-12-21-project-final.html 2007-Dec-12: The Final Project has been posted. You must either take the final exam or complete this assignment. I would not recommend doing both. Project 8 for 2007-Dec-12 http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-12-12-project-8.html 2007-Dec-12: Project 8 has been posted. Enjoy! Corrections to Project 7 http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-12-02-project-7.html

2007-Dec-02: Project 7 contained a few errors. In particular, there was a reference to a NumberParser class, as well as a mention of real-valued numbers. That was old material that I failed to remove before posting the assignment, and can safely be ignored. In fact, it has now been removed.

Additionally, I failed to specify whether leading zeros were legal. Although I will not penalize you for accepting them, ideally, strings that have leading zeros on an otherwise well-formed integer should be rejected as malformed.

Project 7 for 2007-Dec-02 http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-12-02-project-7.html Here is Project 7, due on 2007-Dec-02. Enjoy! Lab time for 2007-Nov-14 Due to popular request, we will have lab today in SMudd 014. Cancelled lab for 2007-Nov-12 I am out sick, so lab is cancelled today. Please continue work on Project 6, and feel free to send questions. If there is demand for it, we may hold a lab time on Wednesday. Also watch for the posting of Project 7, coming soon. Project 6 for 2007-Nov-16 http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-11-16-project-6.html Here is the complete description of Project 6, where you will implement and time the execution of various sorting algorithms. Solutions to the mid-term exam http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/mid-term-solutions.pdf Here are the solutions to the mid-term exam. Check them out, let me know if you have questions, complaints, etc. Help session on Monday, 2007-Nov-05 I apologize that I (lazily) never confirmed or disconfirmed this evening's lab session. With apologies to those who showed up on speculation, sorry for wasting your time, since I was, ultimately, unable to hold the session tonight. So, instead, we will have a Monday, 2007-Nov-05, 8:00 pm help session at my house. Bring your laptop if you have one, and be ready with your questions. We'll provide dessert, and, I hope, some useful tips. Project 5 for 2007-Nov-07 http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-11-07-project-5.html At long last, I've posted a complete description of Project 5, which is now due on Wednesday, 2007-Nov-07, at 11:59 pm. Sample mid-term exam http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/sample-mid-term.pdf Here is a sample mid-term exam. Remember that there may be topics addressed by this mid-term with which you are not familiar. Its true purpose is provide examples of the types of questions that I am likely to ask on this Wednesday's mid-term exam. Corrected Friendly cell results http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/index.html You must re-copy the results files for the Friendly cells, as my original versions were incorrect. For more information on how to do that, see the corresponding annoucement on the class web pages. Lab time today (again) Today, we will meet in the lab to do some work on Project 4. Project 4 for 2007-Oct-19 http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-10-19-project-4.html The Project 4 page is now available. It's lacking a little bit of detail, but most of what you need is there. Note that this project depends heavily on inheritance, which we are covering right now. Changing date help/lab session at my house! I am moving the date of the help/lab session at my house from today to tomorrow. So, do not show up tonight (Tuesday), since there will be no session. Instead, show up tomorrow (Wednesday) at 8 pm at my house for time to work on your project with a little support. Project 3 for 2007-Oct-05 http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-10-05-project-3.html The Project 3 page is posted. Please note the due date, which is just before the long fall weekend break begins. Lab time today Today, we will hold class in the lab (SMudd 014) again to continue discussion and work on the Game of Life. Project 2 for 2007-Sep-23 http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-09-23-project-2.html At long last, here is Project 2, due on 2007-Sep-23. Note that it recommends (and describes) the use of the Scanner class instead of the Keyboard class, thus eliminating any reliance on settings in your .cshrc file. Corrections for 2007-Sep-17 lab information http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-09-23-project-2-corrections.html I made two mistakes during today's lab. First, I erred in telling you what to place in your .cshrc file in order to get the Keyboard methods to work. Moreover, I also incorrectly referred, during lab, to the Keyboard.readLine() method, which does not exist. So, I've posted corrections that will provide the correct information. cs12-submit problems solved? I believe that I've fixed all of the problems with the cs12-submit program. If you have not tried it since 9 am today, go ahead and try it on remus or romulus again. Project 1 for 2007-Sep-16 http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-09-16-project-1.html A few days overdue, check out the formal posting for Project 1, which includes instructions on submitting your work. Assignment for 2007-Sep-07 http://www.cs.amherst.edu/~sfkaplan/courses/fall-2007/cs12/assignments/2007-09-07-solve-towers.html Check out your first assignment, due on 2007-Sep-07.
