Question

Create the class CharacterReader that has the following properties: protected string field named data. public default constructor that assigns the empty string to data. public get accessor methods for data. public virtual void method named Add() that takes one char parameter. It add the parameter to the end of data. Create the class UniqueCharacterReader that, has the following properties: publicly inherits CharacterReader. public default constructor that assigns the empty string to data. public overridden Add() that only mid the parameter to the end of data if the character is not already in data. Create the class SortedCharacterReader that has the following properties: publicly inherits CharacterReader. public default constructor that assigns the empty string to data. public overridden Add() that add the parameter to data and sort data in ascending order. In the main, create a pointer array of CharacterReader that contains an element, for each class (it has three (3) elements in all). Next, use a loop to randomly add hundred (100) characters each of the elements of the array. Add the same characters to each element and only mid uppercase letters. Last, display data for each element.
