Version Three

Because we are now using an array with ten elements, instead of ten different variables, it is possible to dramatically shorten our program by using a for loop.

Does this convince you of the utility of arrays? If not, consider what changes would be required to the first version of our program if you wanted to read 100 numbers. Compare that to the changes that would be required in our latest version.
