windows cmd says have problem on line 29 "end" part. can't figure out. can please help?

you've got number of problems here need fixed before can working program.

first up, if x == || b not mean think does. evaluates if x == (a || b) compare first string, not second. test against multiple possible matches best approach use case:

case (answer) when 'hello', 'hi'   # matches! else   # not matched end

you can break out several different conditions adding additional when clauses, , can use regular expressions catch variations in case, , forth.

as added in comment, nested if pattern needs go away. need switch state system instead:

state = :greeting  loop   case (state)   when :greeting     puts "<input greeting below>"     case (gets.chomp)     when "hello", "hi"       state = :how_are_you     else       break     end   when :how_are_you     puts "hey, how you?"     case (gets.chomp)     when "i'm good", "i'm doing well"       state = :thats_good     else       break     end   # ... additional `when` clauses.   end end
