P In this exercise, you modify the program from Lab 5-2 in Chapter 5. If necessary, create a new project named Intermediate21 Project. Copy the instructions from the Lab5-2.cpp fi le into a source fi le named Intermediate21.cpp. (Alternatively, you can enter the instructions from Figure 5-33 into the Intermediate21.cpp fi le.) Change the fi le name in the first comment. Modify the program so that it uses two value-returning functions: one to determine the fat calories and the other to determine the fat percentage. Save and then run the program. Test the program appropriately.
