Create a program that allows the user to enter an unknown number of sales amounts for each of three car dealerships: Dealership 1, Dealership 2, and Dealership 3. The program should calculate the total sales. Display the total sales with a dollar sign and two decimal places.

a. Create an IPO chart for the problem, and then desk-check the algorithm using 23000 and 15000 as the sales amounts for Dealership 1; 12000, 16000, 34000, and 10000 for Dealership 2; and 64000, 12000, and 70000 for Dealership 3.

b. List the input, processing, and output items, as well as the algorithm, in a chart similar to the one shown earlier in Figure 8-16. Then code the algorithm into a program.

c. Desk-check the program using the same data used to desk-check the algorithm.

d. If necessary, create a new project named Intermediate19 Project, and save it in the Cpp8\Chap08 folder. Enter your C++ instructions into a source file named Intermediate19.cpp. Also enter appropriate comments and any additional instructions required by the compiler.

e. Save and then run the program. Test the program using the same data used to desk-check the program.
