Class Definition and Main


Program Description

Create a class, named IntSet, that implements a set that will store integer values in the range of 0 through 1000, inclusive. (Use a static const for this upper bound, so that the value can be modified, and your program re-compiled, to work with an alternate value.) If you don't remember the basics of sets and set operations, you may find the set entry at Wikipedia helpful. The required member functions are described below.

You must use the code from the provided class definition and main function. Do not modify the provided code, except where indicated or to add comments, without consulting me. Don't forget to add all the proper array and object error checking.

Your constructor must allow between zero and five elements to be inserted into the set initally.

Your member functions insertElement and deleteElement should work by adding (or deleting) the specified element to the set.

The toString member function should return a string containing standard set notation.

example sets:
{1, 2, 4, 6, 34, 58}

The member function equals should have an integer set as its parameter and return type bool. It should determine if two sets have exactly the same members.

The intersection and union functions should be called intersectionOf and unionOf. Both should take two integer sets as their parameters and perform the requested operation by modifying the contents of the object on which it was invoked.

// s1 becomes the union of s2 and s3

The member function hasElement should have return type bool and determine if the parameter is an element of the set.

See starter file (intset-stub.cpp) for the required class definition and main function.

What to turn in

For this assignment, you will be creating a project with several files. All of your project files should be placed in a directory named 19-3 inside your home directory on Pengo. This directory should not contain any files not part of your project. I will collect all of the files from this directory.
