  Objectives: Continue practicing past concepts Practice building basic C++ classes Practice building C++ classes that use inheritance Assignment: For this lab you will be given a driver file (main.cpp) and two text files (potatoList.txt and appleList.txt) that will be testing classes that you should create. You should not change any of these files. (Note: For your main.cpp -- feel free to comment out portions in development if you don't have a particular class working yet. For changes, we are referring to changing what a particular line actually does/how it does it.) Your job will be to create the classes that will enable this main file to work. There should be three classes: Inventory (base class) Apple (derived class) Potato (derived class) Once you create your classes and are finished, the final project should statically print out what is contained in the code execution portion. That is how you know that you have completed the program The classes you should create are outlined below in UML Class diagrams. For a UML class diagram cheat sheet, refer to the last page of the lab assignment details. UML Specifications:  . Inventory: o getItem Total(int quantity) - returns the item's price multiplied by the parameter quantity o is Organic() - acts as a standard getter o setOrganic(int flag) - takes in an integer -- if the integer is 1 organic should be true, else if the integer is 0, it should be false o getters/setters - act as usual Apple o Apple() - standard empty constructor -- takes all items and sets them to their empty counterparts ("" for strings, O for numbers -- false for booleans); statically sets itemName to "Apples" o Apple(with parameters) - takes in user parameters to set apple and inventory data equal to; statically sets itemName to "Apples" For organic: see setOrganic standards above o getters/setters - act as usual Potato o Potato() - standard empty constructor -- takes all items and sets them to their empty counterparts (*" for strings, O for numbers -- false for booleans); statically sets itemName to "Potatoes" o Potato(with parameters) - takes in user parameters to set apple and inventory data equal to; statically sets itemName to "Potatoes" For organic: see set Organic standards above o getPotato Total(float weight) - returns the weight parameter multiplied by the price of the potato o getters/setters - act as usual Inventory Apple Potato -type: string - orchardLocation: string - type: string #itemID: string #itemName: string #stock: int # price: float #organic: bool + Apple + Apple(string type, string location, string itemID, int stock, float price, int flag) + Potato + Potato(string type, string itemID, int stock, float price, int + getitemIDO: string + netitemName string flag) + Sellype(Shiny type).
