Question

C++

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.
