Write a program that reads a person's name
in the following format:

first name, then middle name or initial, and then last name.

The program then outputs the name in the following format:

Last_Name, First_Name Middle_Initial.

For example, the input:

Mary Average User

should produce the output:

User, Mary A.

The input:

Anne H. Dawson

should produce the output:

Dawson, Anne H.

You program should work the same way
and place a period after the middle initial
even if the input did not contain a period.

Your program should allow for users who 
give no middle initial or middle name.
In that case, the output, of course,
contains no middle name or initial:

Anne Dawson

should produce the output:

Dawson, Anne

If you're using C strings, assume that each name 
is at most 20 characters long.

Alternatively, use the class String.

Hint: You may want to use three string variables
rather than one long string variable for input. 
And you may find it easier ***not*** to use getline.
