Write a C++ program that reads a persons full name from the keyboard. The user can either input their name as first middle last or first last. Your program should then output their last name first followed by a comma, so either last, first middle or last, first respectively. (Note: You must ensure that regardless of which way the user enters, the program will proceed past your last cin line without any extra input.)

Example 1 input: Allie Funk Example 1 output: Funk, Allie 

Example 2 input: Jon Raymond Garbe Example 2 output: Garbe, Jon Raymond
