/*
 * Calculate the Average of Given Array
 * -------------------------------------
 * 
 * This is one basic program using array.
 * Steps
 * 1. Declare a variable sum with 0
 * 2. Iterate the array and add with sum variable
 * 3. Divide the sum with array length
 *
 * array = {10, 10, 10, 10, 10};
 * sum is 50
 * array length is 5
 * average is 10
 * 
 * array = {10, 20, 30, 40, 50, 60, 70, 80, 90, 100};
 * sum is 550
 * array length is 10
 * average is 55
