## 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 parameters is not 1, or if there are no words, the program displays a newline (`'\n'`).
