Program $1(100$ Points toward Course Grade$)$

Design an Inventory class that can hold information for an item in a retail store's inventory. 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 on hand

cost

A double that holds the wholesale per$-$unit cost of the item

The class should have the following public member functions.

Member Function

Description

default constructor

Sets all the member variables to $0$

constructor #$2$

Accepts an item's number, quantity, and cost as arguments. Calls other class functions to copy these values into the appropriate member variables. Then calls the setTotalCost function

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 the item number, quantity, or cost$.$ The program output should look like the picture below. Extra credit is given if you use the header file to create a more professional looking output display.

Programming Project $1$

Create a UML diagram for the inventory class with RAPTOR and a flowchart that uses the class.

Name the Visual Studio Project folder $($replacing LastName and FirstInitial with YOUR name$)$: LastName$\_$FirstInitial$\_$Program$1($example: Smith$\_$J$\_$Program$\_1).$

Your class should be split properly into $2$ files: the specification $(.$h$)$ file and the implementation $(.$cpp$)$ file. Both of these files should be named the same as the class name.

Your client program should be split properly into $3$ files: the header $(.$h$)$ file, the main source file $(.$cpp$),$ and the function's source file $(.$cpp$).$

Delete BOTH debug folders found inside your project $($use Windows Explorer to do this$)$ BEFORE zipping your project in the next step.
