In this exercise, you modify the program from Computer Exercise 23. If necessary, create a new project named Intermediate24 Project and save it in the Cpp8\Chap12 folder. Copy the instructions from the Intermediate23.cpp file into a source file named Intermediate24.cpp. Change the filename in the first comment. In addition to displaying the average high temperature and average low temperature, the program should also display the highest temperature stored in the first column in the array and the lowest temperature stored in the second column. Save and then run the program. Test the program using the data shown earlier in Figure 12-19.

Exercise 23:

If necessary, create a new project named Intermediate23 Project and save it in the Cpp8\Chap12 folder. Also create a new source file named Intermediate23.cpp. Declare a seven-row, two-column int array named temperatures. The program should prompt the user to enter the highest and lowest temperatures for seven days. Store the highest temperatures in the first column in the array. Store the lowest temperatures in the second column. The program should display the average high temperature and the average low temperature. Display the average temperatures with one decimal place. Save and then run the program. Test the program using the data shown in Figure 12-19.
