Chapter 8, Problem 6PC

CashRegister Class

Write a CashRegister class that can be used with the RetailItem class that you wrote in Chapter 6’s Programming Challenge 4. The CashRegister class should simulate the sale of a retail item. It should have a constructor that accepts a RetailItem object as an argument. The constructor should also accept an integer that represents the quantity of items being purchased. In addition, the class should have the following methods:

The getSubtotal method should return the subtotal of the sale, which is the quantity multiplied by the price. This method must get the price from the RetailItem object that was passed as an argument to the constructor.
The getTax method should return the amount of sales tax on the purchase. The sales tax rate is 6 percent of a retail sale.
The getTotal method should return the total of the sale, which is the subtotal plus the sales tax.

Demonstrate the class in a program that asks the user for the quantity of items being purchased, and then displays the sale’s subtotal, amount of sales tax, and total.

Dijkstra's Algorithm (part 1). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values. Write down your final [correct] answer, as you‘ll need it for the next question.
