Design a grocery product class named Product that has the following private member variables: PLU of type string name of type string type of type int price of type double inventory of type int

and the following public member functions (do not write a constructor. The compiler will automatically generate an implicit constructor): setProductAttributes: mutator to set the PLU, name, type, price and inventory of a Product. The arguments should be in that order setInventory: mutator to set the inventory getPLU: accessor to get the PLU getName: accessor to get the name getType: accessor to get the type getPrice: accessor to get the price getInventory: accessor to get the inventory

Demonstrate the class in a program, as specified below.

1. Additional Requirements

a) What to turn in

Your should turn in the following files: Product.cpp which contains the function description of all the member functions main.cpp file which contains the main function. You should write Product.h, but do not turn it in. It is already on zylabs. Product.h contains the class definition and the function prototypes of all the member functions (no in-line functions).

If the user chooses 1, user will be prompted for the PLU and the amount to be added. The program then adds the amount to the inventory and displays the menu again. If the user chooses 2, user will be prompted for the PLU and the amount to be subtracted. The program then subtracts the amount from the inventory and displays the menu again. If the user chooses 3, the program prints the attributes of all the Products. The attributes are the member variable values. If the user chooses 4, the program terminates.

Input validation: The program prints an error message if the user tries to add or subtract from a product whose PLU cannot be found, then displays the menu again. if the user tries to subtract more than what is in the inventory, the program only subtracts what is in the inventory. The menu is displayed again. The program prints an error message if the subtraction or addition amount is not positive. The transaction should not be made in that case. The menu is displayed again.

c) File

The file contains product records. Each grocery product record consists of the following 5 items: - PLU code: Product Look Up Code. Unique for each product, stored as a string. - Product Name, stored as a string - Product Sales Type: 0 = per unit, 1 = per pound - Price per Pound or price per unit, - Current Inventory Level (pounds or units). Below is an example of file content. In this example, there are four records, and each line corresponds to a record.

You may assume the records are properly formatted, and therefore there is no need for input validation when reading from the file.

d) Style

Make sure you follow the style requirements, especially regarding the comment header for functions, to avoid losing points.

2. Extra credit (20 points)

For the extra credit, your main function should implement, in addition to the basic version, the following feature. If the user chooses 4, the program does not terminate immediately, but prints the history of the past transactions up to 5, then terminates. A transaction is an addition to the inventory level or a subtraction from the inventory level. Transactions that are not made due to invalid input should not be printed. The program should print the transaction #, the PLU, the transaction type (addition or subtraction), and the actual amount added or subtracted. The transaction # is a sequence number assigned to each transaction that is actually executed, starting from 1 for the first transaction. The transactions should be printed from most recent to least recent. If more than 5 transactions were executed, only the 5 most recent transactions are printed.

3. Suggestions for implementation

a) File management

You may read the file twice: the first time to determine the number of records, and the second time to read the content. After the first read, to reposition the read pointer at the beginning of the file, you can close the file and reopen it.

Thanks, will give a thumbs up.
