/*
2. Set up an array to hold the following values, and in this order: 23, 6, 47, 35, 2, 14.
a. Write a program to get the average of all 6 numbers.
b. Using the above values, have your program print out the highest number in the array.
c. Have your program print out only the odd numbers.
d. Sort the array and print.
