Inventory Class

Design an Inventory class that can hold information for an item in a retail stores inventory. The class should have the following private member variables.

Variable Name Description itemNumber An int that holds the items number. quantity An int that holds the quantity of the item on hand. cost A double that holds the wholesale per-unit cost of the item

Member Function Description default constructor Sets all the member variables to 0. constructor #2 Accepts an items number, quantity, and cost as arguments.

Calls other class functions to copy these values into the appropriate member variables.

setItemNumber Accepts an int argument and copies it into the itemNumber member variable. setQuantity Accepts an int argument and copies it into the quantity member variable. setCost Accepts a double argument and copies it into the cost member variable. getItemNumber Returns the value in itemNumber. getQuantity Returns the value in quantity. getCost Returns the value in cost. getTotalCost Computes and returns the totalCost.

Demonstrate the class by writing a simple program that uses it. This program should validate the user inputs to ensure that negative values are not accepted for item number, quantity, or cost.
