Problem with Loop Challenge

The code below correctly solved the challenge despite me commenting out the loops and break statements...

I was receiving the following error while entering in the uncommented version of the code earlier. "Errno::ENOENT: No such file or directory @ rb_sysopen - 1", and after commenting it out and putting "get_answer()" at the bottom, it appears to pass.

Is there are glitch happening on the back end of this challenge?

loop.rb 
# Assume get_answer() is already defined

#loop do
#  answer = gets.chomp
#  get_answer(answer)
#  break if answer == "e"
#end

get_answer()

Hey Daniel,

You are on the right track, but you do not need the gets.chomp method because you are really getting anything. The 'imaginary' "get_answer" method is going to do that for you.

The challenges are very specific and picky, so just really pay attention to the actual wording of the question. The task just wants you to "assign the value of the get_answer() method to an answer variable." You don't need to input a value to the method.

So, the completed code should be:

loop do
  answer = get_answer()
  break if answer == "e"
end

Hope that makes sense and helps. Keep Coding! :)

Thank you for clarifying! Do you know why I was receiving the "Errno::ENOENT: No such file or directory @ rb_sysopen - 1" error from earlier? I wasn't sure what that meant.

I actually am not sure what the error means, sorry. I haven't seen one like that. It could have been just a weird glitch with workspaces.

Then, I shall wear it as a badge of honor that I broke the program! Thanks again!
