Problem with string comparison

ruby-talk

Hi!

The following code:

name = gets.comp.to_s
if name == "Bill" or name == "Steve"
  puts "Wow, you're pretty smart!"
end

yields this error, once executed:

NoMethodError: undefined method ‘comp’ for "Bill":String

What is wrong with the code?

Thanks in advance,

chell

Try

···

name = gets.chomp

Because comp method is not defined for String class, probably what you
want is chomp and you don't need a to_s in the end.

I've found the problem. Apparently, you can't explicitly convert
gets.chomp to a string (it is a string anyways, eh?), so name =
gets.chomp will do fine!

Um sure you can. Its pointless but you can. Your problem was, as many other
people pointed out, that you mispelled "chomp" as "comp".
