In the example at the end of this video (Input and Output | Ruby Basics) the exclamation mark (!) ends up on its own line. That looks very strange. Especially since it's clearly inside the string (between the quotes). What's going on?

Yeah I noticed that, he didn't explain more about "chomp" another string method that will remove newline character like "\n" in whitespace. We need to focus on "gets" function without chomp, it will push all the messages to the next lines which will often happen frequently.
Example:
puts “What is your name?”
name = gets
puts "Hello #{name}!!!!!!"
Hello Mike
!!!!!!
Let's consider to use chomp, see below
puts “What is your name?”
name = gets.chomp
puts "Hello #{name}!!!!!!"
Hello Mike!!!!!!
Prefer to read on Ruby Documentation - Chomp, Chop
Hope that helps. ;)

Courses Plus Student 16,120 PointsThanks, would have been reading ruby docs from A - D (at least) before I'd found that.
