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 memory 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.
