OOP Homework 3 --- Due 12/10 before class

Please email your solutions to Anupam Nandan at anupam.nandan@nyu.edu.
Be sure to use "OOP HW3 Solution" as the subject line.

Assignment 1 (20 Points):

Consider the program hw3.1.cc, which uses the latest version of our
smart pointer class. Provide the correctly ordered list of all method
calls on objects of types Ptr and A that is observed when the program
is executed. You must include calls to constructors, destructors, and
overloaded operators in your list. However, you do not need to list
the values of the parameters to these calls (if there are
any). Explain each method call that you list (why does the call happen
and how does it relate to the program's source code).

Hint: use the TRACE macro to produce the list of all calls.

Assignment 2 (10 Points):

Consider the programs hw3.2.cc and hw3.3.cc, which are variants of
hw3.1.cc. Both of these programs have bugs that can lead to undefined
behavior when they are executed (e.g. crashes). For each program,
explain what is going wrong.
