COSC 072: Computer Science I

Project 3

In lecture, we have started discussing abstract data types, self-referential template classes, and containers. For this project, you'll use a singly-linked list to implement a stack and a queue. Naturally, the classes for these containers must be able to hold any object, so you must implement them as template classes. Specifically, you will implement and use the Node<T> class to implement Stack<T> and Queue<T>.

All of the classes must implement a default constructor, a copy constructor, an overloaded memberwise copy operator (operator=), a size method, an empty method, a clear method, and a destructor. (Not deconstructor! That's POMO. This is C++.) Methods should throw appropriate exceptions, such as bad_alloc, StackEmpty, and QueueEmpty. Use constant parameters and constant methods as appropriate.

It is imperative that you follow our design for the public interface. For Stack<T>, pop must remove and return the object at the top of the stack, push must add an object to the top of the stack, and top must return a reference to the object at the top of the stack. For Queue<T>, dequeue must remove and return the object at the front of the queue, enqueue must add an object to the end of the queue, and front must return a reference to the object at the front of the queue.

Any method that dynamically allocates memory must throw bad_alloc. Any method that returns objects or references to them must throw the appropriate exception when called for an empty container.

To grade your project, we will drop a main function into your directory and compile and run. Our main function will test all aspects of all of your two classes. As a consequence, it is imperative that you test all of your methods thoroughly, preferably as you're developing them.

Instructions for Electronic Submission:

At the top of the file main.cc (or the file containing the main function), place the following header comment, with the appropriate substitutions:
