gistfile1.rb

puts "Enter your name"
name = gets
length = name.length - 1

print "Your name is "
print length
print " characters long."

# ok, so remember what we talked about with .chomp - whenever you use gets, you'll get the extra newline character on the end,
# (\n) - so chomp will remove that. That's why you have to subtract 1 to get the right length, so we can revise the code to the following

puts "Enter your name"
name = gets.chomp
length = name.length
print "Your name is "
print length
print " characters long."

# The other thing that's good to know is that you can use + to concatenate (join together) strings:

puts "Enter your name:"
name = gets.chomp
puts "Your name is " + length.to_s + " characters long."

# We use length.to_s to turn the Integer into a String. Most objects in ruby respond to to_s.
# This pattern, of putting data in the middle of a string, is so common, that there's a shortcut to do it:"

puts "Enter your name:"
puts "Your name is #{gets.chomp.length} characters long."
