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.

Chapter 9

One problem with dynamic arrays is that once the array is created using the new operator, the size cannot be changed. For example, you might want to add or delete entries from the array as you can with a vector. This project asks you to create functions that use dynamic arrays to emulate the behavior of a vector.

First, write a program that creates a dynamic array of five strings. Store five names of your choice into the dynamic array. Next, complete the following two functions:

string* addEntry(string *dynamicArray, int &size, string newEntry);

This function should create a new dynamic array one element larger than dynamicArray, copy all elements from dynamicArray into the new array, add the new entry onto the end of the new array, increment size, delete dynamicArray, and return the new dynamic array.

string* deleteEntry(string *dynamicArray, int &size, string entryToDelete);

This function should search dynamicArray for entryToDelete. If not found, the request should be ignored and the unmodified dynamicArray returned. If found, create a new dynamic array one element smaller than dynamicArray. Copy all elements except entryToDelete into the new array, delete dynamicArray, decrement size, and return the new dynamic array.

Test your functions by adding and deleting several names to the array while outputting the contents of the array. You will have to assign the array returned by addEntry or deleteEntryback to the dynamic array variable in your main function.
