Question

In C++ write an application that calculates total retail values for 5 different shoes entered by the user.

Shoe 1 $15.50
Shoe 2 $27.30
Shoe 3 $34.50
Shoe 4 $42.11
Shoe 5 $54.25

Application must read shoe number and quantity sold for each transaction stdin, compute the total value of that sale, and add the value of that sale to a grand total for that shoe. After all data has been entered, display the total value of each of the five shoe items. Must have driver and a class, must use a switch structure to which shoes sales to update, must use a sentinel controlled loop to determine when the program should stop looping and display result.
Data members
Product price
Total sales for product(in dollars)
Member Functions
One 1 argument constructor(representing the shoe price), set the value of the data member using this argument. Getters and setters for data member, and updateTotalSales method(uses one parameter representing quantity sold and does not return a value) . must use getter and setter methods to access the fields do not access them directly. It computes the total value of the current sale by multiplying the argument passed by the shoess price. It updates the shoes total Sales data member by adding the value calculated in the previous step to the shoes existing totalSales. Must use getter and setter functions. Do not access the data members directly.

Main function
Instantiate 5 separate objects of the class Shoe, passing the appropriate argument to each constructor. The Shoe class constructor requires the price of that instance of the shoe. The prices can be hard coded numbers.
Using Sentinel controlled loop
1.   Read the shoe number and the quantity sold for one transaction.
2.   Use a switch statement to determine which Shoe objects sales to update.
3.   Call the appropriate Shoe objects updateTotalSales function.
4.   Continue loop until user enters 0 for the shoe number.
5.   After the loop is complete display each shoe objects total sales, including the dollar sign, two decimal places with a field width of 10.

Sample run
Shoe number: 2
Quantity sold: 4
Shoe number: 1
Quantity sold: 3
Shoe Number: 5
Quantity sold: 2
Shoe number: 1
Quantity sold: 2
Shoe number: 5
Quantity sold: 3
Shoe Number: 4
Quantity sold: 2
Shoe Number: 0

Total Sales
Shoe 1 : $77.50
Shoe 2: $109.20
Shoe 3: $0
Shoe 4: $84.22
Shoe 5: $271.25
