Quick question here, I am using Sublime Text to follow along with this lesson and I noticed an issue with whitespace. When I try to print strings to multiple lines they are running together and I am forced to include "\n" in the string. What could be causing this? See my code below:
year = 2014 print "The year is #{year}\n" #\n is for linebreak
future = 5 print "In #{future} years, the year will be #{year + future}\n"
If I do not include the "\n" all of the lines print out as one. Any suggestions to get the desired line breaks I am seeking?
