The function does the following:

* Takes a `first_name` and `last_name`.
* Converts the first letter of each one to upper case with `title()`.
* <abbr title="Puts them together, as one. With the contents of one after the other.">Concatenates</abbr> them with a space in the middle.

### Edit it { #edit-it }

It's a very simple program.

A função faz o seguinte:

* Pega um `first_name` e `last_name`.
* Converte a primeira letra de cada uma em maiúsculas com `title()`.
* <abbr title = "Agrupa-os, como um. Com o conteúdo de um após o outro.">Concatena</abbr> com um espaço no meio.

### Edite-o { #edit-it }

É um programa muito simples.

Mas agora imagine que você estava escrevendo do zero.
