Question

In C++

Antique Class

Each Antique object being sold by a Merchant and will have the following attributes:

• name (string)
• price (float)

And will have the following member functions:

• mutators (setName, setPrice)
• accessors (getName, getPrice)
• default constructor that sets name to "" (blank string) and price to 0 when a new Antique object is created
• a function toString that returns a string with the antique information in the following format

<Antique.name>: $<price.2digits>

Merchant Class

A Merchant class will be able to hold 10 different Antique objects and interact with the user to sell to them. It should include the following attributes:

• antiques (array): An Antique array of 10 objects
• quantities (array): An Integer array representing the quantity of each Antique object in stock. This can range from 0 to 10.
• revenue (float): variable used to store the total amount of money earned by the Merchant after each sale

And will have the following member functions:

• Merchant (constructor): the constructor takes as arguments an array of Antiques and an array of quantities to use them to initialize antiques and quantities. revenue should be set to 0.
• haggle: function that decreases each and every Antique object's price by 10%. It will print the following:

You have successfully haggled and everything is 10% off.

Customer cannot haggle more than once. If he tries to haggle more than once, it will print the following:

Sorry, you have already haggled.
