Hi, I’m trying to get my file to take in a list of names (a firstname,  
surname and middlename) and to then list each part of the name with an  
index. For example one name “John, Smith, Paul” should be printed as  
1.John  
2.Smith  
3.Paul

I can list the index as 1.John S. Paul but am unsure on how to list  
each part of the name seperately, does anyone have any ideas?

Create one array with all the strings in it. Or define Person#each or  
Person#to\_a.

“John, Smith, Paul”.split(", ").each\_with\_index do |name, index|  
puts “#{index + 1}. #{name}\n”  
end
