Question

I’m trying to get out of a while loop when the input is this:

BYE
BYE
BYE

And not this:

BYE BYE BYE

The code is:

my_reply = ((word1 = gets) + (word2 = gets) + (word3 = gets))

while my_reply != ((word1 == 'BYE') and (word2 == 'BYE') and (word3 == 'BYE'))
    puts 'Grandma: ...'
    my_reply = ((word1 = gets) + (word2 = gets) + (word3 = gets))
end

puts 'Grandma: ' + 'Fine, sonny, don\'t hang out with your aging grandmother!'.upcase

which is not working. I need help.

Answer 1

gets also returns the line feed and carriage return “\r\n”, e.g. “BYE\r\n”. This means you have to strip them out before comparing to other strings. (see String.strip)

while [gets, gets, gets].map(&:strip) != ['BYE', 'BYE', 'BYE']
  puts 'Grandma: ...'
end

puts 'Grandma: ' + 'Fine, sonny, don\'t hang out with your aging grandmother!'.upcase
