Chris Johanson wants a program that calculates and displays a 10%, 15%, and 20% tip on his total restaurant bill. First, create an IPO chart for this problem, and then desk-check the algorithm twice, using $35.80 and $56.78 as the total bill. After desk-checking the algorithm, list the input, processing, and output items in a chart similar to the one shown in Figure 3-23, and then enter the appropriate C++ declaration statements.
