# How can I make it cycle through the whole array without 
# having to edit c_list[number..number]? Is there a way to 
# automate that, so I only have to add cities to c_list 
# without having to add more code?

of course, just do

  clist.join(' pets || ')



eg irb session,

irb(main):012:0> c_list=%w(Boston Nashville)
=> ["Boston", "Nashville"]

irb(main):013:0> c_list.join(' pets || ')
=> "Boston pets || Nashville"

irb(main):016:0> c_list += %w(Portland Atlanta Chicago)
=> ["Boston", "Nashville", "Portland", "Atlanta", "Chicago"]

irb(main):017:0> c_list.join(' pets || ')
=> "Boston pets || Nashville pets || Portland pets || Atlanta pets || Chicago"

irb(main):018:0> c_list += %w(Indianapolis Charleston Boston Nashville)
=> ["Boston", "Nashville", "Portland", "Atlanta", "Chicago", "Indianapolis", "Charleston", "Boston", "Nashville"]

irb(main):019:0> c_list.join(' pets || ')
=> "Boston pets || Nashville pets || Portland pets || Atlanta pets || Chicago pets || Indianapolis pets || Charleston pets || Boston pets || Nashville"
