In this exercise, you modify the program from Lab 7-2 in Chapter 7. If necessary, create a new project named Introductory16 Project and save it in the Cpp7\Chap10 folder. Copy the instructions from the Lab7-2.cpp file into a source file named Introductory16.cpp. (The Lab7-2.cpp file is contained in either the Cpp7\Chap07\Lab7-2 Project folder or the Cpp7\Chap07 folder. Alternatively, you can enter the instructions from Figure 7-52 into the Introductory16.cpp file.) Change the filename in the first comment to Introductory16.cpp. Modify the program so that it uses a void function to determine the grade. Save and then run the program. Test the program using the following scores and sentinel value: 45, 40, 41, 96, 89, and –1. The total points and grade should be 311 and B, respectively.
