warning: string literal in condition

Question

Using the first bit of code below I receive two warning messages: warning: string literal in condition x2

if input == \"N\" || \"n\"
  #do this
else         


        

Answer 1

I was also looking for the answer to this question, and thanks to a friend found a few other solutions.

1) Change the case for the input so you only have to make one test:

if input.downcase == "n"

2) Use a more sophisticated check on the input data:

if %w{n N}.include?(input)     or
if ['n', 'N'].include?(input)

The second one allows for far more flexibility with your checking , especially if there are groups of entry you are looking for.

Hope what I found helps others.
