Instructions

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

• A word is a section of string delimited by spaces or by the start/end of the string.

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

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