Inventory Class

Design an Inventory class that can hold information and calculate data for items 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 item number.

quantity: An int for holding the quantity of the items on hand.

cost: A double for holding the wholesale per$-$unit cost of the item

totalCost: A double for holding the total inventory cost of the item $($calculated

as quantity times cost $).$

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, cost, and quantity as arguments.

The function should copy these values to the appropriate

member variables and then call the setTotalCost function.

setItemNumber: Accepts an integer argument that is copied to the

itemNumber :member variable.

setQuantity :Accepts an integer argument that is copied to the quantity

member variable.

setCost :Accepts a double argument that is copied to the cost

member variable.

setTotalCost :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 $.$

getTotalCost: Returns the value in totalCost $.$

Demonstrate the class in a driver program.

Input Validation: Do not accept negative values for item number, quantity, or cost$.$

$1-$ Design a class with the name Inventory that holds fourth attributes:

a$.$ Declare one attribute called the itemName of char $*$ type.

b$.$ Declare one attribute called the itemNumber of int type.

c$.$ Declare one attribute called the quantity of integer type.

d$.$ Declare one attribute called the cost of the floating point type.

$2.$ Use this pointer notation in your member's functions.

$3.$ Handling an exceptions through quantity and cost it should not have negative values. Define two new classes NegativeQuantity and NegativeCost.

$4.$ Implement your code with Constructors, Destructor, Copy Constructor, Mutators, and Accessor functions.

$5.$ Overload Member$-$wise, Insertion$/$ Extraction operators $=,<<,>>$ of Inventory Class..

$-$ Define an object's array of dynamically allocated memory in the driver program, and perform the following operations by options menu and switch$/$case statement.

a$.$ Insert and verify that the ID number of the item does not exist in the array.

b$.$ Remove an item from the array by itemNumber.

c$.$ Show an item from the array by itemNumber..

d$.$ Update the item data by itemNumber.

e$.$ Sort the items by the class itemName.

f$.$ Display all the items of the array.

g$.$ Quit the program

$6.$ The solution must contain the following:

a$.$ Source code.

b$.$ Separate class specifications from implementation.

c$.$ Program output.

d$.$ Descriptive Tables.

e$.$ UML diagrams.
