What are the disadvantages of designing an ADT to be a pointer? E.g. you create an instance of the ADT with the express purpose of it only accessing data through a pointer?
Homework Answers
The disadvantages of designing an ADT to be a pointer are:
(1) It causes many inherent problems in dealing with pointers
.
(2) Comparisons between objects do not work as expected, because
they are only pointer comparisons (rather than pointed-to value
comparisons)
(3)The implementation of the abstract type cannot control
allocation and deallocation of objects of the type (creating a
pointer to an object with a variable declaration and use it without
creating an object).

C++ Question Create the ADT of the Phone class. Phone uses three integer variables that describe a phone number. Example: Part1: 123, Part2: 456, Part3: 0001 describes the phone number (123)456-0001. Also, add to the Phone ADT class any constructor, any accessor and any mutator function that you may find helpful. Also, add the precondition and postcondition of each function. If you could add comments to explain what you are doing that would be very helpful, but not necessary. Thank...
