Redo Programming Project 6 from Chapter 9 (or do it for the first time),

but this time encapsulate the dynamic array and array size within a

class. The class should have public member functions addEntry and

deleteEntry. Make the array and size variables private. This will require

adding functions for getting and setting specific items in the array as well

as returning the current size of the array. Add a destructor that frees up the emory allocated to the dynamic array. Also, add a copy constructor and overload the assignment operator so that the dynamic array is properly copied from the object on the right-hand side of the assignment to the object on the left-hand side. Embed your class in a suitable test program.
