Using the knowledge of OOP in Go, Build simple classes for the following “objects”

• Car
• Product
• Store

The Car class can have any car attributes you can think of.

The Product class should have attributes of a product i.e (the product, quantity of the product in stock, price of the product). A car is a product of the store, but there can be other products so the attribute of the car can be promoted to the Product. The Product class should have methods to display a product, and a method to display the status of a product if it is still in stock or not. The Store class should have attributes like

• Number of products in the store that are still up for sale
• Adding an Item to the store
• Listing all product items in the store
• Sell an item
• Show a list of sold items and the total price
