Modify assignment $13-6($Inventory Class$)$ to read in information from a file $($Inventory$.$txt$)$ to create Inventory objects that are, then, stored in an Inventory array of another object named dept $($for department$).$Then, print each of the objects that comprise the department$$s inventory.

$>>>$ Prefix all new fields and functions with your initials $($e$.$g$.$ fk$\_$newfield$)<<<$

Modifications should be made to the Inventory class as follows:

$1.$ Add a string variable named description to the class.

a$.$ Add supporting mutator and accessor functions.

$2.$ Add a function named print to the class to print the following $($bolded letters are

variable names$)$:

itemNumber description $($tab$)$ quantity on hand at a cost of cost$,$ for a total cost of

totalCost.

Create a new class named Dept with the following attributes and methods:

$1.$ Define an Inventory array named products to hold the inventory objects.

$2.$ Define an integer named invItems to hold the total number of different inventory items.

$3.$ Define an integer named invCount to hold the total number of actual inventory items.

$4.$ Define a double named invCost to hold the total cost of all inventory items.

$5.$ Feel free to define any work fields that you choose.

$6.$ Define the following functions:

a$.$ Constructor

i$.$ accepts the max number of items to support

ii$.$ dynamically allocates space for the products array

iii. no default constructor offered

b$.$ addItem accepts the fields needed to create an inventory object and adds the object to the furniture array.

c$.$ getinvItems that calculates and returns the number of different inventory items.

d$.$ getinvCount that calculates and returns the total number of actual inventory

items.

e$.$ getinvCost that calculates and returns the total cost of all inventory items.

f$.$ printInv to print the items in the furniture array.

Modifications should be made to the main program as follows:

$1.$ Define a constant in the main program named MAXITEMS and set it to $25.$

$2.$ Define a Dept object named furniture and use MAXITEMS to provide the maximum

inventory items it should allow.

$3.$ Loop through the input file $$Inventory$.$txt$$ and use the data in it to initialize as many items in the furniture object as the data allows.

The format of data in Inventory.txt is $$itemNumber$,$ quantity, cost, description$$ as

follows:
