Deaf Calculus

Luke Kyrchner

Hey, I am trying a variation of Deaf Grandma program that takes off of
Tintin's Character Professor Calculus. I tried to make it... But it did
not work very well. Any help/advice?

Instead of putting .capitalize, you put .upcase
What I would like to know is how to put in a random sentence, like you
make 7 different sentences, how could you make the program put a
sentence at random instead of a date?

Just a hint.

'daygs' used for "Snatch" reference :)...

array = ["Ya like daygs?", "Do I like daygs?", "Yeah, d'ya like
daygs", "Oh, 'do I like dahgs.'", "Yeah, I like dahgs."]
puts array[rand(array.size - 1)]

I think you want puts array[rand(array.size)], otherwise the last
element won't ever be used.

------------------------------------------------------------ Kernel#rand
rand(max=0) => number
------------------------------------------------------------------------
Converts _max_ to an integer using max1 = max+.to_i.abs+. If the
result is zero, returns a pseudorandom floating point number
greater than or equal to 0.0 and less than 1.0. Otherwise, returns
a pseudorandom integer greater than or equal to zero and less than
max1.

Yes, yes; must read the docs before responding :-)
