I've posted all scores including extra credit etc. I've figured
a rough estimate of the course grade assuming you perform in the final
as you have in class.
The number of points before the final is limited to 300. There are 200 in the final. The final typically determines your course grade.
Best of luck.... and have a good summer.

I hope we can post the pre-final grading tonite or tomorrow afternoon.
The final exam is 2-3:50pm on Wednsday 17th of June, as scheduled.
Course grades will be posted when we get them done.

I've posted the latest grades.... but they don't have a complete set
of Lab10 yet -- if you are a Monday lab person my estimate
of your course grade may be a little low. We will update these
by Tuesday morning.
The blank sheets show you how I will be scoring the final, and calculating the grade for the course.
See you Monday for the last [ 20.html ] class.

The finals start on the Tuesday of that week. Our CS202 final is on the Wednsday (June 17th) from 2pm to 3:50pm. It is the deadline for all extra credit work -- projects and seminar reports.

Since we had a disk drive crash last night I'll accept late questions
on Algorithms and Chapter 19 until 1pm today. The answers may suffer:-(
Todays class is about the Laws of Computer Science -- these are mostly deep and difficult to graps with out mathematics. However one of them is pretty much common knowledge: Murphy 's Law which states that "If Anything can go wrong, it will!" This law was first promulagated in the Airforce base near Adelanto in the Second World War as a philosophy of testing.
We had a perfect example this morning -- I sent out an email inviting Email questions almost 5 minutes before the server came online again.

Grades are published at [ grading/ ] on this web site.
I've just discovered that the [Contact] button has been silently failing. The [Question] button had been updated to the new web server at the start of the quarter. I failed to do the samething with the "mailme" script used in the [Contact] button. I will be working to fix this today. Meanwhile.... if you have used the "[Contact]" button to send me questions or work it has been lost. If you evidence I will backfill the credit. My grovelling apologies.
By the way -- If had engineered the web site properly then this problem would not have arrisen. Each time you ignore the advice our book gives you accumulate "technical debt" which one day will have to be paid off.

2009-04-20 Mon Apr 20 10:48 Late Questions on Chapter 8
Chapter 8 pages 411 -- Pointer Operators (LATE)
can the variable yPtr have different values in the same program?
Yes, that pointer can (1) refer to different int variables at different times, and (2) the pointer referes to a location that can have different values at different time.
With pointers it can help to keep the "two values" distinct... the location refered to, and the value in that location.
Chapter 8 pages 455 -- Pointers LATE
Can you tell us more about what the computer does when it is told to use strcat
It must be given two addresses in memory. It starts looking at the characters in one of the addresses, one at a time, going up, until it hits the char '\0' -- the null character. It then starts to copy the other string, starting with its first character being put on top of the null-character, then the other chars....
For example, if we have memory like this
Table
| Variable | [0] | [1] | [2] | [3] | [4] |
|---|---|---|---|---|---|
| s1 | a | b | 0 | ||
| s2 | c | 0 |
| Variable | [0] | [1] | [2] | [3] | [4] |
|---|---|---|---|---|---|
| s1 | a | b | c | 0 | |
| s2 | c | 0 |
Chapter 8 pages 428 -- size of operator
What does the sizeof operator do exactly, and when do you use it?
The compiler looks at "sizeof" and replaces it by a number indicating the number of bytes (chars) needed to store the data. It can be applied to a variable or the name of a type, or the name of a class.
Notice it calculates the size as seen before the program runs. It will not tell you how much actual data is in a dynamic object at run time.
Chapter 8 pages ppp-ppp -- classes
why do we use classes?
To make our program more understandable and easier to change. It has many independent pieces, all with a meaning. So we know where to find the code that needs changing.... and some idea of what to do with it.
Don't forget -- chapter 10 is next.
The first set will be ready by Monday afternoon.
2009-04-15 Wed Apr 15 10:04 Deadline for chapter 8 has passed

2009-04-15 Wed Apr 15 08:02 Chapter 7 is too late now
The deadline to earn points for questions on topics in chapter 7 -- arrays and vectors
was 10am on Monday. I will post quick answers here. You will have an oportunitiy to go back
to previous a previous chapter in the last class before the final.
To earn points today the questions must be on chapter 8 -- check [ 04.html ] and [ schedule.html ]
We also have a project due today. If you want any points it must be handed in by the start of today's class.
Next week we move on to chapter 10....
All subscripts in C/C++ start at 0.
All subscripts in C/C++ start at 0.
All subscripts in C/C++ start at 0.
Be very clear in your thinking and check every subscript you write, at least twice.
Chapter 7 pages 378 -- Arrays
Whats the difference between a one-dimensional and two-dimensional array?
A one dimensional array has one subscript. A multi-dimensional array have more than one subscript. The Dimension of an array is equal to the number of subscripts.
Chapter 7.9 pages ppp-ppp -- Multidimensional Arrays
When referrencing an array element incorrectly as a[x,y] why does it only read only 'y' and not 'x'?
The comma in an expression in C/C++ means: discard the first value
cout << ((1+2+3),(4+5+6)) <<endl;will output a single value -- 11. The 7 will vanish.
Chapter 7 pages 365 -- arrays
could you explian linear search for arrays a little better ??
We must move on. We will return to searching and sorting later. Meanwhile try running the linear search algorithm on paper.

Some one asked me what the book when I teach this class in the Spring
quarter 2009. It is the same book
(starting in Chapter 8) as cs201:
Required Text "C++ How to Program" by Deitel and Deitel, 6th Edn., ISBN 0-13-615250-3. It should be in the book store. Used and cheap copies should be OK, but do not buy older editions. You can also read it, a page at a time, online, for free, on campus or through the Pfau Library Proxy.... This is only good for emergences.
See you all in the Spring.
Not I'll by revising this site "Real Soon Now". The schedule will change to fit the new book. The objectives and teaching techniques should be similar to what you find here.

My nephew may be attending Cal State shortly, so feeling a bit nostalgic, I decided to contact some of my professors. I'm not sure if you remember me, but I'm sure you remember my friend <anonimized> (yes, that was a joke). I admit that I thought most of your classes were a waste of time, but I was very wrong. I've built several successful companies, and now own a multi-million dollar corporation, all because of my knowledge and use of computer science. Since I graduated, I've found innovative ways to integrate my knowledge of computer science into every business I've owned. So, I suppose this is a thank you letter to let you know that I credit people like you with my success. If my nephew does attend Cal State (I'm trying to convince him), I'm recommending you as an instructor.

I've decided to publish a copy

of the CSci2002 Final examination from Fall of 2002. This
was a course based on a different book. There is no guarantee
that the new final will be similar -- I always make some small changes,
and the change to Scansholm forces to make some big ones. However
the layout, format, instructions, and most of the content
will be the same.
