THIS IS A C++ CODE. Your significant other has had a flash of inspiration - the world needs another inventory management program! You agreed to write it for them because love is indeed blind. Create a class with at least the following fields: • Item Description • Quantity at Hand (Cannot be negative) • Wholesale Cost (Cannot be negative, nor less then 5 dollars) • Retail Cost (automatically calculate 100% markup) • Date Added to Inventory (System should enter this) Create a numeric style menubar which allows the following tasks: • Add new records to inventory. • Display any record in inventory. • Change any record in inventory. • Delete any record in inventory. • Exit the program. • Validate the menu selection (Do not allow other choices) Constraints. • Use input validation for the data. • You should be able to store an unlimited number of items. Create a dynamic memory structure to do this. • Use file I/O to save and recall your data. • Load the data file when the program starts and save the data file when you quit. • Use OOP methods and the standard style issues from earlier homework • Calculate and display the wholesale value of the inventory. • Add a menu item to dump the entire inventory to screen. • Display output as a webpage.
