CSC 148H: INTRODUCTION TO COMPUTER SCIENCE

Old Announcements -- Week 3

Sunday 26 January: Assignment 1: Adding your own subprograms

Question: I am in the process of writing the code for one of my procedures and am realizing that it will be quite lengthy and complicated. So I was wondering if we were allowed to create our own subprograms.
Answer: Yes, you can add any subprograms of your own -- and there will certainly be times when you should.

Sunday 26 January: Assignment 1: linked list code almost ready in OOT

The linked list code will be ready in OOT tonight. Follow the Assignments and Tests link below, or click here.

Sunday 26 January: Assignment 1: linked list code ready in C

The linked list code is ready in C. It is available under the Assignments and Tests link below, or here. Also note on that page that two files in the array version have been updated since Friday. Please pick up the new versions.

OOT students: Your linked list code will be available shortly.

Friday 24 January: Assignment 1 code ready

Starter code for assignment 1 is available under the Assignments and Tests link below, or here.

Friday 24 January: Assignment 1 code coming

The starter code for assignment 1 is not available yet. The array version will be up later today, and the linked list version should be up by Sunday. You can get well into the assignment using only the array version.

Wednesday 21 January: Assignment 0 stuff

Some miscellaneous things about assignment 0:

• Don't worry about inputs that cause errors. All input and output is handled by our code, so you have no control over it. Just make sure your functions work.
• In the OOT version of FindLongestSequence, the comment preceding the second loop says that it is not checking the diagonal starting from (1,1). In fact, it does check it. This was a mistake. It is inefficient, and of course inconsistent with the comments, but it does no harm in terms of producing the correct answer.

Wednesday 21 January: remote access to the PC lab

Question: Can I use "telnet" from work to access my CDF account?
Answer: No, there is no remote access to the PC lab. You can't phone in directly or telnet in. There are few times during the course where you'll need to work specifically on our machines. Probably only when handing in A0 and A3a (the two very small assignments).

Wednesday 21 January: C students: A0 starter code

As we discussed in class, some of your compilers have complained about this part of the starter code:

   void
   findLongestSequence (boolean IM[][], int *lengthOfSeq, int *i, int *j,
                        int numRows, int numCols)

As I announced, if you have this problem you may eliminate it by adding in dimensions for the IM parameter, as follows:

   void
   findLongestSequence (boolean IM[MAXROWS][MAXCOLS], int *lengthOfSeq, int *i, int *j,
                        int numRows, int numCols)

Wednesday 21 January: Cancellation

Diane's office hours on Monday January 27th and Tuesday January 28th are cancelled. There is a possibility that I will also not be here for my hour on Wed the 29th. If you need help on those days, please attend the office hours of Professor Fich or Holt, or a TA office hour. (Remember that you are welcome to attend the office hours of any of the 148 professors.)

Wednesday 21 January: Missed the OOT sale?

Question: I am still interested in purchasing a copy of the OOT program. Is there going to be another sale date?
Answer: No, that is the only planned sale date. You can still buy the software at the regular price. Check the UofT computer store or call Holt Software Associates.

Wednesday 21 January: C students --- Don't use C++

Some students have asked whether they can use any C++ commands, particularly the input/output commands, which are a little more convenient. You are not permitted to use any C++ commands until assignment 3. For now, your programs must be written completely in ANSI C.

Wednesday 21 January: Last batch of 148 accounts

The final batch of 148 accounts has been created. A complete list of all accounts is available on my corkboard.
