In this exercise, you will modify the tip program shown earlier in Figure 7-31. Follow the instructions for starting C++ and viewing the ModifyThis16.cpp file, which is contained in either the Cpp8\Chap07\ModifyThis16 Project folder or the Cpp8\Chap07 folder. 

(You may need to open the project/solution file first.) Change the for statement to a while statement. Save and then run the program. Test the program using 90.50 as the restaurant bill. The three tips should appear as shown earlier in Figure 7-32.

Problem specification Create a program that allows the user to enter the amount of a restaurant bill. The program should calculate and display the suggested amounts to tip a waiter using rates of 10%, 15%, and 20%. Use a counter to keep track of the three rates.
