Feel free to make any necessary changes to the file provided - it compiles but does not necessarily work at present.
Bring a printout of your audit code to class on Monday 1/22/07 - we will share the code around the room and discuss briefly what worked well about auditing and what was difficult.
I've also provided support code in the form of Ptr.h and PtrInterface.h to help make your code compile. These files were taken from CS249 and should not require tweaking.
