Marcy's Department store is having a BoGoHo (Buy One, Get One Half Off) sale. The store manager wants a program that allows the salesclerk to enter the prices of two items. The program should both calculate and display the total amount the customer owes. The half-off should always be taken on the item having the lowest price. For example, if the items cost $24.99 and $10, the half-off would be taken on the $10 item.

a. Create an IPO chart for the problem, and then desk-check the algorithm twice. For the first desk-check, use 24.99 and 10 as the prices. For the second desk-check, use 11.50 and 30.99.

b. List the input, processing, and output items, as well as the algorithm, in a chart similar to the one shown earlier in Figure 5-37. Then code the algorithm into a program.

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

d. Enter your C++ instructions into a source file named Introductoryl2.cpp. Also enter appropriate comments and any additional instructions required by the compiler. Display the total amount owed in fixed-point notation with two decimal places.

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