Chapter 14, Problem 4RQE
Explanation of Solution
Friend function:
All members of the access specifiers public, private, and protected of a class can be accessed by a friend function.
- Friend functions are not the member functions of a class.
- The function prototype for the friend function is declared inside the class.
- Even though the function is not considered as the member of the class.
- The keyword “friend” is used to represent that the function is the friend function.
- All non-friend functions of the class can access the public members in the class.
- But the friend function of the class can access all the public, private, and protected members in the class...

Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm.

The CashRegister class should be able to internally keep a list of RetailItem objects. The class should have the following methods: A method named purchase_item that accepts a RetailItem object as an argument. Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list. A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list. A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list. A method named clear that should clear the CashRegister object’s internal list. Demonstrate the CashRegister class in a program that allows the user to select several items for purchase.
