Test the program using different computer IDs, prices, and rates. When you are finished testing the program, enter the letter x as the computer ID.

Follow the instructions for starting your C++ development tool. Depending on the development tool you are using, you may need to create a new project; if so, name the project Lab15-2 Project and save it in the Cpp8\Chap15 folder. Enter the instructions shown in Figure 15-18 in a source file named Lab15-2.cpp. (Do not enter the line numbers.) Save the file in either the project folder or the Cpp8\Chap15 folder. Next, you will add a header file to either the project folder (if you are using Microsoft Visual C++) or the Cpp8\Chap15 folder (if you are using Dev-C++ or Code::Blocks). The instructions for doing this are shown in Figure 15-19. (If you are using a different C++ development tool, you will need to ask your instructor how and where to add a header file.)
