In this exercise, you modify the program from Lab 11-2 in the chapter. If necessary, create a new project named Intermediate24 Project and save it in the Cpp7\Chap11 folder. Copy the instructions from the Lab11-2.cpp file into a source file named Intermediate24.cpp. (Alternatively, you can enter the instructions from Figure 11-58 into the Intermediate24.cpp file.) Change the filename in the first comment to Intermediate24.cpp. Add three additional functions to the program: displayAverage, displayHigh, and displayLow. The functions should display the average rainfall amount, the highest rainfall amount, and the lowest rainfall amount. Save and then run the program. Test the program appropriately.
