Instructions

Write a program that takes an argument and displays its first word, followed by a newline ('\n').

• A word is a sequence of characters delimited by spaces or by the start/end of the argument.

• The output will be followed by a newline ('\n').

• If the number of arguments is not 1, or if there are no words, the program displays nothing.
