For this assignment, you will create a new derived class treasureChest from boxType. Startwith the baseline code on Canvas for rectangleType and boxType, and add the following toboxType:• Create an enumerated type for color – valid colors are green (green = 0), black (black = 1),brown (brown = 2), and white (white = 3). (Note: you can choose other, appropriate valuesfor your colors.)• Add a boxColor as a private member variable to boxType along with a setBoxColormutator and getBoxColor accessor.• Modify the parameterized constructor for boxType to take a parameter to set boxColor.The default constructor should set boxColor to green.Next, derive treasuC++代写 Assignment 2代写C/C++实验reChest from boxType using public inheritance. treasureChest has thefollowing properties:• Note: this description is deliberately not a UML class diagram or similar. You should sketchan outline in pseudocode for your new class as you read these descriptions (and the client)to ensure you meet all the requirements. (You don’t have to turn your sketch in.)• A treasureChest can store treasure! Treasure in this case will be represented by astatic array of 100 coins. Use an enumerated type to represent a coin, with thefollowing three types and values: gold (value 25) silver (value 10) copper (value 1) nada (value 0)• A treasureChest has a current total number of coins that are stored. Keep track ofthis with a private member variable of appropriate type. The default is 0, i.e., the chest canhold 100 coins but starts empty (all elements in array are set to “nada”).o Create an appropriate accessor to return the total number of coins currently in thechest.• Treasure can be added to the chest via a class method that takes a coin denomination andplaces it in the next available slot in the array of coins (i.e., the next slot with “nada”).• Treasure can be removed from the chest one piece at a time with a method that takes acoin as input parameter and removes one coin of that type from the array (if any of thattype are present).• The color of the treasureChest is restricted to black or brown:o The treasureChest constructors should set boxColor appropriately (recall thedefault box color is green).• Add a method called getSum to return the total value of all the coins in the chest.Note: you will test your solution with an unmodified copy of the client supplied on Canvas.What to turn in:1. Your header (.h) and source (.cpp) files for rectangleType, boxType andtreasureChest.a. You may modify rectangleType and boxType as needed. But you must keep theprivate members as private.2. A copy of the client (it should be unmodified, but this makes it easier to test your code).3. Your output after running the test code in the provided, unmodified client.4. All documents should be uploaded to Canvas following the assignment submission instructions(linked on Canvas).转自：http://ass.3daixie.com/2019030852505412.html
