Grandma has hearing issues ‘cos she’s getting old. All she does is
answer my questions with a phrase "NO NOT SINCE 1938’. If I don’t
yell(.upcase), she’s gonna tell me to speak up. If I yell without a
question mark, she’ll tell me “THAT’S NOT A QUESTION!”. I write a
program for this scenario and anytime I yell with or without a question
mark, she tells me “THAT’S NOT A QUESTION!”
What am I doing wrong or at least what am I missing?
question = ‘’
puts ‘Ask grandma something…’
while question != ‘BYE!’
question = gets.chomp
if question != question.upcase
puts ‘HUH?! SPEAK UP, SONNY!’
elsif question == question.upcase+’?’
puts ‘NO, NOT SINCE 1938!’
elsif question == question.upcase
puts ‘THAT’S NOT A QUESTION!’
elsif question == ‘BYE!’
puts ‘BYE!’
end
end

Try adding this and see if it gives you a hint:
question = ‘’
puts ‘Ask grandma something…’
while question != ‘BYE!’
question = gets.chomp
puts question
puts question.upcase
puts(question.upcase + '?')
if question != question.upcase
puts ‘HUH?! SPEAK UP, SONNY!’
elsif question == question.upcase+‘?’
puts ‘NO, NOT SINCE 1938!’
elsif question == question.upcase
puts ‘THAT'S NOT A QUESTION!’
elsif question == ‘BYE!’
puts ‘BYE!’
end
end
Hint: the condition that question has to be equal to question.upcase +
‘?’ is wrong. Check here
Class: String (Ruby 1.8.7) and see if you can
find a method that tells you if the string ends with (hint, hint) a
question mark.

Try like this: question == question.upcase[0…-1]+‘?’

Read the documentation. It helps understanding.

Good luck!
Try like this: question == question.upcase[0…-1]+’?’
That did the trick 
thanks a lot. That said though, I don’t understand
what the “[]” is all about as I’m a beginner programmer, I haven’t come
across that in my studies as of yet until now. You mind explaining what
it means and what it did?

Do not get confused!
You can access characters within a string with []
Do you have IRB?
If not, install it.
If yes, use it.
Start IRB do this:
x = “foobar”
x[0…3] # => “foob”
x.upcase[0…-1] # => “FOOBA”
Within the [] you specify a range or the start/end position for the
character.
I just had a go with this and tried for at least an hour before getting
here. I read a few responses and gave it another go, read some more and
finally got it. A little change here or there, not much though. I
noticed my “rand” part with the dates is different from everyone elses
but it works just how i imagined it too. And the assigning of response I
picked up from aother person that made it easier for me to understand is
tucked nicly inside the first action as to include it in the looping
effect.
puts ‘Hi Sweety, it’s Grandma!’
bye = 0
while bye < 3
if ((response = gets.chomp) == “BYE”)
puts “GOOD BYE, SONNY!”
bye = (bye+1)
end
if (response != response.upcase)
puts ‘HUH?! SPEAK UP, SONNY!’
bye = 0
end
if (response == response.upcase and response != “BYE”)
puts ‘NO, NOT SINCE ‘+(rand(1930…1951)).to_s+’!’
bye = 0
end
end
This sure was a tough one without knowing bout all the functions you
needed to know. There was a lot left to imagination, like the thing that
pushed my RUBY into being finished was the “AND” function in my 3rd if
statement. When ever I would type “BYE” it would also tell me "NO, NOT
SINCE 19xx! and then also GOOD BYE SONNY!.. I just couldn’t figure
out how to exclude something from the “puts” and it also would make the
bye value set to 0 when it used both responses cause I set it so if
“BYE” wasn’t used it would reset the value of “BYE” back to zero. All in
all this excerise was almost easy enough to do it without help or hints
but not quite. Made me want to know though and pushed me to try really
hard but I just feel with the info adding up to the “TRY IT OUT” part in
the pickaxe just didn’t stick well enough or just didn’t have the parts
told to you yet? Might just be me but I definately struggled.
Nice, I started programming with Chris P.'s book too a little under a
year ago. I still have fond memories of the exercises in there. Keep at
it, man!
