Mountain Coffee wants a program that allows a clerk to enter the number of pounds of coffee ordered, the price per pound, and whether the customer should be charged a 3.5% sales tax. The program should calculate and display the total amount the customer owes. Use an int variable for the number of pounds, a double variable for the price per pound, and a char variable for the sales tax information.

a. Create an IPO chart for the problem, and then desk-check the algorithm twice. For the first desk-check, use 5 as the number of pounds and 13.69 as the price per pound; the customer should be charged the sales tax. For the second desk-check, use 3 as the number of pounds and 11.59 as the price per pound; the customer should not be charged the sales tax.

b. List the input, processing, and output items, as well as the algorithm, in a chart similar to the one shown earlier in Figure 5-27. 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 Introductory11 Project, and save it in the Cpp8\Chap05 folder. Enter your C++ instructions into a source file named Introductory11.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. Test the program using the same data used to desk-check the program.
