Ruby The Solution

My code for this challenge

print "when you include \\t in a double-quotes string in Ruby, the output looks like this:\nbefore\tafter\nWhen you include \\n in a double-quoted string, the output looks like this:\nbefore\nafter\n\nThe first \"before\"/\"after\" pair should have a single tab character between them,\nNOT space characters.\n"

correct ?

Im guessing you used print instead of puts in order to practice the escape sequence a bit better right?

Hi, Ahmed!

Copied your code into Workspaces, and it runs just fine!

Here are some additional options:

puts 'When you include \t in a double-quoted string in Ruby, the output looks like this:'
puts "before\tafter"
puts 'When you include \n in a double-quoted string, the output looks like this:'
puts "before\nafter"

Alternately, we can make a Ruby heredoc like this:

puts <<-EOF
When you include \\t in a double-quoted string in Ruby, the output looks like this:
before\tafter
When you include \\n in a double-quoted string, the output looks like this:
before
after
EOF

It might not seem particularly profound to another reader, but my mind was just blown. I realized how many different ways there must be to arrive at the same console return, even with a simple program like this.

I did this

puts "When you include \\t in a double-quoted string in Ruby, the output looks like this:\nbefore\tafter"

puts "When you include \\n in a double-quoted string, the output looks like this:\nbefore\nafter"

I haven't learned about the Ruby heredoc yet.

# this is a quick tutorial on how to use escape sequences inside ruby. 

# When you include \t in a double-quoted string in Ruby, the output looks like this:

puts "\tYeer!"

# before  
puts "  Yeer!"
# =>    Yeer!

#after
puts "\tYeer!"
# =>    Yeer!


# When you include \n in a double-quoted string, the output looks like this:

puts "Yeer!, im feeling like,\n\"Woah\"!"

# before
puts "Yeer!, im feeling like,"
puts  ""Woah"!"

# =>  SyntaxError ((irb):1: syntax error, unexpected tCONSTANT, expecting end-of-input)
# => "Yeer!, im feeling like, "Woah"!"
...                           ^~~~

# after
puts Yeer!, im feeling like,\n\"Woah\"!"
# => Yeer!, im feeling like,
# => "Woah"!

# The first "before"/"after" pair should have a single tab character between them,
# NOT space characters.

puts "/tbefore and  after"
# =>   before and after


#before 
puts "  before and after"
# => "  before and  after"

#after
puts "\tbefore and  after"
# => "  before and after"
