Let’s try one more method (er, two methods). As you might have guessed, the
.downcase methods convert a string to ALL UPPER CASE or all lower case, respectively.
.upcase on your name to make your name ALL CAPS and use
puts to print it to the screen, like this:
puts "eric".upcase # ==> ERIC
On the next line, call
.downcase to make your name all lower case. Make sure to use
puts so you can see it printed out!
