JUST help me with Display and Cost in class Product:

IN c++

class Product: derived from InventoryItem class (minimum implementation specified below).

• Private member data: name (string), quantity (integer) and price (double).
• Public static data:
  • const string (name): "No Product".
  • const int (quantity): 0
  • const double (price): 0.99
• Constructors (use member initializer syntax)
  • Default constructor: set member data to static data's default values above. Must explicitly invoke the base class' default constructor.
  • Non-default constructor: take five parameters (id, restocking, name, quantity and price). Must explicitly invoke the base class' non-default constructor.
• Destructor: output "Product: , Name, quantity, price , restocking destroyed ...".

• Public member functions:
  • accessors/mutators for name, quantity, price.
  • Display: invoke Display from base class, then display its own data. NOTE: If the product restocking is true somehow indicate it using "special effects" such as ***** or whatever effect you'd like.
  • Cost: take an integer as its only parameter representing the quantity (how many products to be sold) and return the total cost (price * quantity parameter).

I just need some demo code. About the base class display, just to show me where and how to reference it.

Thank you
