### 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'`).
