Sum and Average of a Number in C++

I wrote this program 10 years ago in my C++ programming class in college where I am teaching here in Bacolod City, Negros Occidental Philippines. This program uses a one-dimensional array as its data structure to ask the user to give five numbers and then the program will calculate the sum and average of the five numbers and display the results on the screen.
