Exercise #9

This exercise is about understanding some existing code - you don't write any new code.

The file /cse/courses/cse333/13au/ex10.tar.gz (on department machines like attu) contains a slightly more annotated version of the code we started looking at in class today. That code prints messages when constructors, destructors, or assign operators are invoked (as well as at other times). You should run the code and make sure you can understand why each line of its output appears (and possibly why no other lines that you might have expected do not appear).

Having done that, hand in a file that contains all and only those lines of output that are caused by executing this line in main.cc

  returnedVal = sub(local_clone);

Operational Notes:

• The code starts by monkeying around with the default constructor (the one taking no arguments). Read the comments in Example.h - there are four steps to work through. When you're done, you'll have commented out two lines of the mainline (plus you'll know a lot about the default constructor). Until you get to that point, the code won't (or at least probably won't) run.
• There is a makefile. You can say make run to build and run. You don't have to use the makefile, however.
