Subject: Codelab assignment 3 "run time error"

(This message is being sent to all CPSC 101 section 302 students)

In constructing these functions you may get a message saying
something like:

 >    Your code contains a run-time error. That means that the
 >    code is correct from a language point of view but is doing
 >    something 'illegal' at run-time: accessing an invalid memory
 >    location, dividing by zero, or something like that. CodeLab
 >    should be able to be more specific but can't. However, if
 >    you click the FEEDBACK button and  tell us that this
 >    happened, we will get back to you with advice. Be sure to
 >    report the following status code: 39

For this assignment this message is misleading. Unless you have
done something truly off the wall, this almost certainly means:

 > "YOUR FUNCTION RETURNED AN INCORRECT ANSWER (or forgot to
 > return anything at all))"

So please DONT use the FEEDBACK button to complain to Codelab!!

Since the first two functions are trivial, this message is most
likely to be obtained on the last problem.

If that is the case, here is what you should do.

(1) Go back and review quiz 6(the program tracing problem)

(2) Now apply the methods of quiz 6 to your program using
    3 and 4 as parameters and see...

(3) if you actually return the proper values that are provided
    in the statement of the assignment

If not,  then you need to work on your program until it DOES
produce correct values for input parameters 3 and 4.

If you believe that it DOES work and will send me a quiz 6
type trace showing that you DO get the correct answer for 4
as a parameter, I'll be glad to show you where you went
wrong in your trace!
