CS201: Introduction to Computer Science
2010-03-15 Mon Mar 15 13:30 Grades posted
I've posted the latest grades. For your information at this time the grade distribution looks likeTable
| A/A- | B+/B/B- | C+/C/C- | D+/D/D- | F |
|---|---|---|---|---|
| 6 | 10 | 7 | 1 | 1 |
(Close Table)
But your grade will depend on what you show you know in the final... so prepare well!
The next class [ 19.html ] is about arrays -- both one and two dimensional.
Then we have a review [ 20.html ] session with a chance to ask any qustion about the content of CS201 that you like.
2010-03-11 Thu Mar 11 09:41 Question about project
The idea is that you add the UML diagrams to the printout of the
program. You could even draw it by hand on the printout --
as long it is readable. If you do it on a separate sheet, staple it to the
old printout.

I met the electricians by the elevator as they were leaving
and thanked them for getting the power back to our systems.
It was knocked out by a treble power cut yesterday evening...
Any way the latest grades [ ../grading/ ] have been posted.
The next class [ 17.html ] is on C++ vectors...
I'm hoping that we will hit a run of good techluck.
2010-03-04 Thu Mar 4 15:03 Class 16 today
In class students coded this UML diagram.
![[Horstmann page 244]](16Employee.gif)
The C++ code is on page 244 of the book.
We then looked at the code in the next lab [ lab09/ ] and drew the UML class diagram.

2010-03-01 Mon Mar 1 13:41 Grades posted and campus closing
The campus will be closed to save California some money on Tuesday.
The class work is at
[ 16.html ]
and the lab is
[ lab08/ ]
and thay are about working remotely with programs that spread over several
files.
The Thursday class starts with you handing in a report
(SHORT) on your experience on Tuesday, a review question
+answer
on UML and your latest project. This class
[ 16.html ]
will be on the
UML and will include a quiz on your project and how classes
work.

2010-02-17 Wed Feb 17 09:20 Added review questions
I've just selected some review questions from chapter 5 and put them in
[ 12.html ]
,
[ 13.html ]
, and
[ 14.html ]
so please reload these before completing your study of the text book sections.
Next class is number 12.
2010-02-16 Tue Feb 16 13:49 Change of project schedule P6 and P7 swapped
I've switched P6 and P7 arround to fit with the reading.
2010-02-15 Mon Feb 15 13:34 Grades Posted
Next class
[ 11.html ]
(case study and testing)
and
[ lab06/ ]
(lab).
Exercises for today
[ assert.cpp ]
[ foobar.cpp ]
2010-02-09 Tue Feb 9 14:21 Exercise in class today
We developed
[ circ.cpp ]
today. Most of this code will appear in a future lab...
2010-02-08 Mon Feb 8 13:29 Updates...
I've posted the latest grading.... and made some of the easier changes
that you have suggested to the web site. I'm working on the
experiments in the future labs.
Next we introduce "functions" [ 09.html ] and do [ lab05/ ] on loops and decisions...
Then, Thursday, we have more on functions in [ 10.html ] with Project4 due and a quiz.
Then we will be half way through the quarter!
2010-02-01 Mon Feb 1 14:08 Grades Posted
I've just posted
[ grading/ ]
that includes the projects and quiz from last week. Please check
these for errors.
The next class is [ 07.html ] on loops. It is followed by [ lab04/ ] that goes over logic and loops.
On Thursday [ projects.html#P3 ] is due in, P2 can be resubmitted, and there will be a quiz testing your ability to trace a program with arithmetic and string operations.
2010-01-29 Fri Jan 29 10:14 Using Boolean Expressions not Ifs
This morning I realised that the "george.cpp" program can be simplified because any program that
has
if( A )
B=true;
else
B=false;(where A is a condition and B is bool) can have this code replaced by
B = (A);which is simpler but more sophisticated. Here [ george2.cpp ] is a running program that tests this idea.
I will have to go back to the notes on class 06 to add something about the input and output of bool values.
2010-01-28 Thu Jan 28 14:47 Class 6 and 7
In class today I showed you a program that evaluates a given
Boolean expression with two variables
[ george.cpp ]
and I'm planning to use a version of it in Lab04 on
Tuesday.
I'm currently rewriting lab04 and lab05...
The next class is [ 07.html ] and after the last day to drop. There is the usual reading and review questions.
2010-01-27 Wed Jan 27 10:50 First Grades Posted
If you have returned your pinword form go to
[ grading/ ]
and input it in to the form. Then click "[OK]"
top see your grades on the line marked "***" plus a few statistics.
More information will be posted every monday afternoon from now on.
2010-01-20 Wed Jan 20 16:32 Changes
I've improved
.see ./04.html
and started on
[ 06.html ]
ready for next week.
I have also put up [ vi.intro.html ] which introduces the 'vi' editor for people working remotely.
For more help with Linux -- come the the club meeting Friday 5pm in JBH356 and followed by a Games Night!
We should trace some programs to day...
2010-01-19 Tue Jan 19 19:11 Program written in class today
We wrote and tested
[ gravity.cpp ]
today in class. I also demonstrated our UNIX/Linux command
~dick/bin/Q noviceand the 'vi' technique
:set numberto see the numbers on the lines of the files we write.
The next class is [ 04.html ] on non-numeric data types -- strings and ready made objects. Hand in what ever you have done on P1 and be ready for a quiz on it and chapters 1 and/or 2.
Note -- the books special data types: Time, Employee, Point, Line, Circle, and Window are all available on our lab machines and "Q" will find them for you...
2010-01-13 Wed Jan 13 11:01 Correction to web site
First, thanks to Daniel, who discovered that the link to SSH329 in the syllabus
is broken. I have changed
[ ../syllabus.html ]
to link to a university in Germany and one in Hawai instead.
Secondly, I discovered that my [ projects.html ] had several errors (example listing a nonexistent project, and omitting a vital one) and fixed that.
The next class is [ 02.html ] in reviews chapter 1 in the book.
Next I start improving lab02, class 03, ....
By the way, I am pleased that Mr. Wengzhe Xue will be assisting me in the labs and with the grading for this class this year again.
2010-01-06 Wed Jan 6 14:55 Working on first class and lab
Today
[ 01.html ]
and
[ lab01/ ]
are being polished... These documants are ready:

2009-11-17 Tue Nov 17 10:22 Preparing for the Winter 2010 Quarter
I will be teaching CSCI201 in the winter 2010 quarter with a new text
that is very similar to one I used some years ago.
Items redacted after this point
2009-03-25 Wed Mar 25 09:34 Grading done
I finisihed grading the final, and unless you can find an error
these will be the grades for the course.

I've posted my first final and course grades for you to check. They may change if any errors come to light or bonusses are earned.
Currently we have

2008-02-13 Wed Feb 13 10:02 Questions on functions etc answered online + project feedback
I've also started grading you projects. Here are some common errors.
These are nearly all examples of intelligently
jumping to a completely false conclusion.
Table
| Basis | Guess | Correct |
|---|---|---|
| Because everything else I do is easy | This should be easy | Programming takes a lot of time, care and attention to detail |
| I'm in a hurry | I'll skip writing an algorithm it will save time. | You will get lost and confused when you don't plan. |
| For loops can declare a varible "for (type name = ..." | While loops can also do this | They can't. |
| Semicolons are at the end of statements | They can't be inside a for loop: "for(...,....,...)...". | They MUST be in a for loop: "for(...;...;...)..." |

2007-11-29 Thu Nov 29 14:11 Syntax sheets
I've uploaded Andrew's Syntax sheets as PDF file ready for download: [ Syntax2columns.pdf ] [ SyntaxFullSize.pdf ]
I hope they help..... even if I feel it is always better to develop
one's own cheat sheets....
2007-11-15 Thu Nov 15 13:11 PI and Books on C++ in the library
This is in response to a lunch time meeting with a student.
Books on C++ can be found in the library with call number
QA76.73.C153
(PI): The best way to get π, e, etc into your program is to do this
#include <cmath>
const double PI = 4.0*atan(1.0);
const double E = exp(1.0);
const double ROOT2 = sqrt(2.0);These formulas automatically supply an accurate value without you having to type lots of decimal digits. By putting them outside of all the functions and classes you request that they are evaluated before the program starts running.
