In C++

Implement a program that tracks customers purchases. Create the following classes. Use appropriate access modifiers (member variables should be private!) and data types for each. Dont forget to add getter and setter functions. Item: This class has the attributes (member variables) called title, description, and price. It has a pure virtual function called print that prints the type and description of the current object to the console. This function is NOT implemented in this class but must be implemented/overridden in the three subclasses below. o Book :This class inherits from Item. It has an instance variable called page Count. o Movie : This class inherits from Item. It has an instance variable called length. o CD : This class inherits from Item. It has an instance variable called trackCount. ShoppingCart :This class keeps track of items that were bought.It has a single constructor which expects the maximum number of items that can be placed in the cart. It must have a dynamically allocated array of pointer to an item object (Item* array = new Item*[size]) which is initialized in the constructor. The cart must have functions to add an item and print the items currently in the cart to the console by calling each objects

print

() function. Customer: The customer class stores an id, the first name and the last name and a pointer to a shopping cart object which gets initialized in the constructor. Finally, implement a main function that creates a customer. Then add one item of each type to the customers shopping cart and list the items in the cart on the console. * Note : fields, attributes, properties, member variables, instance variables all refer to the same thing: variables defined inside a class as part of an object, not inside functions!
