Looping Problem
 

Hi. I'm new to ruby and i am trying to get a while not loop to occur if
the answer i got from gets wasn't capatalized. This is what i have now:

while not answer3.upcase
puts "WHAT!"
answer3=gets
end

It's not working and i've also tried answer3= .upcase and such. Thanks
in advance for the help.

The String#upcase method returns a string which is equal to the string
it is called on with all the letters converted to upper case. If you
want to check that a string has no lowercase letters, you could use
"answer3 =3D=3D answer3.upcase" as your condition. If you want to check
that a string is capitalized (which is slightly different), "answer3
=3D=3D answer3.capitalize" is more likely to be what you want.

Untested:

class String
def is_upper?
self =3D=3D upcase
end
end
