### 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 a newline(`'\n'`).
