Write a program that accepts any number of homework scores ranging in value from 0 through 10. Prompt the user for a new value if they enter an alphabetic character. Store the values in array. Calculate the average excluding the lowest and highest scores. Display the average as well as the highest and lowest score that were discarded.

This program is written in C++

Note that the average is calculated without the highest and the least value.
