Christmas tree

This application was written as a solution to a personal challenge to write a simple, self-contained application written in C++.

This application will accept a positive number between 5 and 80 input by the user, and return an ASCII representation of a Christmas tree with a seasonal greeting.

Please enter the size of your tree (between 5 and 80):

Enter a postive number between 5 and 80 and hit ENTER. A Christmas tree will be generated whose bottom row will be represented by a number of asterisks equal to the number entered, if an odd number, or rounded up to the next odd number, if an even number was entered. For example, if 30 is input by the user, the bottom row of the tree will have 31 one asterisks.
