Question: I have to write a program that lets the user enter in as many numbers as he wants and determine which is the largest, smallest, what the sum is, and the average of all the numbers entered. Am I forced to use arrays to do this or is there another way? If I have to use an array, can someone help me out with an example of how I should be approaching this question? Thanks

Answer: 
The newline character `\n` should be included between the double, however HTML does not allow for line feed, but Thomas Hunter suggested an [hack](https://stackoverflow.com/a/8843665/848250) which consists in using a bunch of white spaces, like so:

```
<%= f.text_area :comment, placeholder: "Comment on your track or                  share your favorite lyrics" %>

```

You can also opt to use the `title` attribute instead.
You're creating HTML code. HTML does not care about whitespace in the actual code. What you need is a break in the HTML itself. However, it seems per this other question [Can you have multiline HTML5 placeholder text in a <textarea>?](https://stackoverflow.com/questions/7189223/can-you-have-multiline-html5-placeholder-text-in-a-textarea) that HTML does not allow line breaks in the `placeholder` field.
