        //  1. a counter

        //  2. to keep track of the sum of the numbers

        //  3. to store the calculated average (use double)

​

        //write a for loop to loop through the array and calculate the sum of the numbers

        //  tip - you must convert your sum (int) to double before dividing

​

        //  tip - you can use the format string "F2"
