Design an Inventory class that can hold information for an item in a retail store's inven- tory. The class should have the following private member variables. Variable Name Description itemNumber An int that holds the item's number. quantity An int that holds the quantity of the item onhand. cost A double that holds the wholesale per-unit cost of the item A double that holds the total inventory cost of the item (calculated as quantity times cost). totalcost The class should have the following public member functions. Member Function Description default constructor Sets all the member variables to 0. Accepts an item's number, quantity, and cost as arguments. The function should call other class functions to copy these values to the appropriate member variables and then call the setTotalCost function. constructor #2 Accepts an int argument that is copied to the itemNumber member variable. setItemNumber Accepts an int argument that is copied to the quantity member variable. setQuantity Accepts a double argument that is copied to the cost member variable. setCost set TotalCost Calculates the total inventory cost for the item (quantity times cost) and stores the result in totalCost. getItemNumber Returns the value in itemNumber. getQuantity Returns the value in quantity. getCost Returns the value in cost. get TotalCost Returns the value in totalCost. Demonstrate the class by writing a simple program that uses it. Input Validation: Do not accept negative values for item number, quantity, or cost.
