CS201: Introduction to Computer Science
- If you are using campus WiFi first use your browser to log into CSUSB's network.
- You need to open a terminal window into your OSX. I'm not sure where
Apple have hidden the icon...
In that window you can input UNIX commands like ssh. Like thisssh -l your_csci_lab_user_id jbh3-1.csci.csusb.edu
- Note: After the ssh there is a minus sign and the letter l, not the digit 1.
- However the next jbh3-1 has a minus and a digit 1.
- When jbh3-1 asks for a password, supply your csci lab password.

2008-03-20 Thu Mar 20 10:03 Preliminary Final Grades Posted
I've posted my first final and course grades [ grading/ ] for you to check. They may change if any errors come to light or bonusses are earned.Currently we have
| Distribution | A/A- | B+/B/B- | C+/C/C- | D+/D/D- | F | W |
|---|---|---|---|---|---|---|
| Frequency | 5 | 11 | 2 | 2 | 1 | 1 |
If you have scored less than 300 points prior to the final you can make up these points by attending seminars in the labs on Friday 21st and getting an essay -- one per presentation -- to me by EMail, or into my dept office box -- by 12noon on Monday.
2008-03-18 Tue Mar 18 14:03 Project 9 Grades Posted
I've got the grades upto the final posted, including scores
on the final project -- see
[ grading/ ]
and check for errors. About half-a-dozen students can benefit by
going to seminars and giving me essays about them -- by monday
afternoon at the latest.
I'm not sure when I will have the final scores posted. Monday at the latest and Thursday afternoon at the earliest.
2008-03-17 Mon Mar 17 12:03 Grades posted
Grades have been posted showing points up to and including
the last class. See
[ grading/ ]
for details. Most people have hit the 300 points limit but some
could benefit from attending and writing a short essay on one of
the 8 seminars
[ ../seminar/ ]
scheduled for Friday.
The final is from 12-1:50 tomorrow. You may bring a single "cheat sheet" of paper -- 8.5><11 inches. You can write anything you want on this sheet. You can write on both sides. You print stuff....
Best of luck.... and I hope you won't need it.

The next project is to write and use a function. See [ projects.html#P6 ] and make sure you actually have declared a function and have a separate main function that calls it. Otherwise you may lose points.
I'm still working on the notes for next Thursday....

2008-02-14 Thu Feb 14 15:02 Computer Problem in Class Today
You saw what happens if a disk fills up on UNIX. Since
it was blocking student's compilations and edits I've worked hard to
remove all large files that I don't need.
I'm now down to the podcasts for this class. I may have to remove the old ones until we get a larger disk drive on the CSE server.
I'm starting to type in questions and answer but don't expect to finish until tomorrow.
2008-02-13 Wed Feb 13 10:02 Questions on functions etc answered online + project feedback
I've posted the answers to your questions in
[ 11.html ]
and have graded your quizzes. Nearly everybody got the correct output.
YEAH!!!!!!
I've also started grading you projects. Here are some common errors that you chould check you code for now to get the jump on the next iteration of this project. Note -- these are nearly all examples of intelligently jumping to a completely false conclusion.
| 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 |
| Because arrays are declared like this "type name[number]" | Vectors are the same "vector<type>name[number]" | vector <type> name ( number ); |
| Because arrays are declared with a size | Vectors must be given a size. | Grow vectors starting with an empty vector: vector <type> name; |
| 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(...;...;...)..." |
| 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. |

I've posted your questions and answers onto

on the CS201 website.
Meanwhile I have got this request
-
Reply_To: me@my.host.domain
I was wondering if you can send me instructions on how to log onto the school server with a mac computer.
I have mac OSX
Which doesn't include the senders EMail address. But I know the name and use their CSUSB EMail plus this page to give a rough answer. You'd get a better one + demo from Scott, our lab assistant.
For example
ssh -l dick jbh3-1.csci.csusb.edu
dick@jbh3-1.csci.csusb.edu's password:
Last login: Wed Jan 23 09:50:29 2008 from jb339-1.csci.csusb.edu
Can anyone give a better answer?

I've graded all the finals that were done.... and posted
the grades at
[ grading/ ]
ready for recording with the university to momorrow morning.
Winter 2008 CSCI201 -- New Book
Meanwhile -- the old text book: "Horstmann" is no longer available
and so I will be redesigning this course for a different book in the
next week. Expect big changes in the syllabus, schedule, web pages,
and plan...
In the Winter we will be covering the first 8 chapters of Skansholm, C++ from Beginning, ISBN 0-201-72168-6. This book is also used in CSci 202 -- but they cover the other chapters.
Sorry for the inconvenience, but this was outside of my control.

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.
