How to Find the Greater Smallest and Average Number of Given Array in C#

This is the best logic building program for beginners in C#. The purpose of this code is to demonstrate the use of functions with array as a parameter in C#. The program will finds the greatest smallest and average of given numbers using array as a parameter.
