Exercise 9: Printing, Printing, Printing

By now you should realize the pattern for this book is to use more than one exercise to teach you something new. I start with code that you might not understand, then more exercises explain the concept. If you don't understand something now, you will later as you complete more exercises. Write down what you don't understand, and keep going.

# Here's some new strange stuff, remember type it exactly.

days = "Mon Tue Wed Thu Fri Sat Sun"
months = "Jan\nFeb\nMar\nApr\nMay\nJun\nJul\nAug"

puts "Here are the days: #{days}"
puts "Here are the months: #{months}"

puts %q{
There's something going on here.
With this weird quote
We'll be able to type as much as we like.
Even 4 lines if we want, or 5, or 6.

Common Student Questions

What if I wanted to start the months on a new line?

You simply start the string with \n like this:

"\nJan\nFeb\nMar\nApr\nMay\nJun\nJul\nAug"
Is it bad that my errors are always spelling mistakes?
Most programming errors in the beginning (and even later) are simple spelling mistakes, typos, or getting simple things out of order.
