"""
  This program takes a user's first and last name, concatenates them with a space in between,
  prints the full concatenated name, and then extracts and prints the last name using string slicing.
  Example:
  If the first name is "John" and the last name is "Doe", the function will print:
  - Concatenated string: John Doe
  - Sub-string (last name): Doe
