## firstword

### 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 arguments is not 1, or if there are no words, the program displays nothing.

### Usage
