Hi,

Did you understand the program just before that?
The one that asked for your full name and printed the number of characters.

Would you show how much you have been able to write so far?

Well this is rather simple. You know how to read from STDIN (= console
input)? There are several ways like gets or readline. So

surname = readline or surename = gets reads from the console and saves
the string in the variable surname. You can get the length of a string
with the length method. So surename.length gives the length of surename
but realize that gets and readline also are saving the newline feed in
the variable you have to cut off with chomp or length will always be 1
to high.

A simple implementation looks like this:

#!/usr/bin/env ruby

$VERBOSE = true

# outputs surname on the screen
puts "surname:"
# reads console input to surname
surname = gets

puts "middlename:"
middlename = gets

puts "lastname:"
lastname = gets

puts "total length:"
# adds the lengths of the three strings after they have beeen chomped
p surname.chomp.length+middlename.chomp.length+lastname.chomp.length

Thanks a lot. I was going about it the wrong way. It looks so simple
now. Thank you!

An excellent book. It's where I learned to program Ruby!

So you'd first want to ask for them. Remember, variables are stored  
from right to left.

#use gets.chomp to ask for the name. Store the result in the  
appropriate variable.
first_name = gets.chomp
middle_name = gets.chomp
last_name = gets.chomp

#Now we need to add these parts together.

And you're fabulous puts code goes here.

You probably had trouble with how to ask for it, right? I know that's  
where I had trouble. puts ing the phrase is just as easy - just puts  
each variable, and separate each with a space.
