Pointers/Inheritance Inventory system In this assignment, you'll make an inventory system for a store's items, including produce and books. The starter program is an inventory system for only produce. 1. Include the price of an item by adding to the ltem class the protected data member int pricelnDollars that stores the price in dollars of an individual item. Write a public function SetPrice with a single int parameter prclnDilirs and returns nothing. SetPrice assigns the value of prclnDilrs to pricelnDollars. Modify the Additem Tolnventory to prompt the user to "Enter the price per item: S", then set the Produce's price to the user-entered value. Modify Produce's Print function output to include the item's individual price. Here is an example output for 20 grape bundles at $3 each that expire on May 22. Grape bundle x20 for S3 (Expires: May 22) 2. Add a new class Book that derives from Item. The Book class has a private data member that is a string named author. The Book class has a public function member SetAuthor with the parameter string authr that sets the private data member author's value. SetAuthor returns nothing The class Book overloads the Print member function with a similar output as the Produce's Print function, except "Expires" is replaced with "Author" and the variable "expiration" is replaced with "author". Here is an example output for 22 copies of Io Kill a Mockingbird by Harper Lee that sells for $5 each To Kill a Mockingbird x22 for $5 (Author: Harper Lee) 3. Modify the AddltemTolnventory function to allow the user to choose between adding a book (b) and produce (p). If the user does not enter 'b' or 'p', then output "Invalid choice" then return the Addltem Tolnventory function. p). If the user does not enter b 4. Create a class named Inventory. The Inventory class should have one private data member:
