first ruby program

ok, so im trying to learn ruby the same way i learn everything else. redo all my 1st year CS homework. is ruby really so stupid that i have to declare 'shit' as a global var for it to be used as an exit for this loop? or am i completely retarded and missing something>?


@shit = 1 #FOR ALL THAT IS FUCKING HOLY
          #when doing a while loop, you must use '@' infront of a variable
          #to make it global. meaning if you want to use mc, dec, ec, et or any other
          #vars inside the while loop, you would have to make them global as well.
          #but this doesnt make sence because none of the examples online are like this.
while @shit == 1
  mc = 8.5
  dec = 9.75
  wc = 10.5
  et = 12.5
  puts "How many milk chocolate"
  mcq = gets.to_f
  puts "How many Dark Euro Chocolate?"
  decq = gets.to_f
  puts "how many white chocolate?"
  wcq = gets.to_f
  puts "how many euro truffles?"
  etq = gets.to_f
  mct = mcq * mc
  dect = dec *decq
  wct = wcq * wc
  ett = et * etq
  subtotal = mct+dect+wct+ett
  if subtotal >= 20 or subtotal <= 39.99
    discount = subtotal * 0.10
  elsif subtotal >= 40 or subtotal <= 59.99
    discount = subtotal * 0.15
  elsif subtotal >= 60 or subtotal <= 79.99
    discount = subtotal * 0.20
  elsif subtotal >= 80
    discount = subtotal * 0.25
  end
  subtotalstr = subtotal.to_s
  discountstr = discount.to_s
  puts "Subtotal = " + subtotalstr
  if subtotal >= 20
    adjsub = subtotal - discount
    puts "discount = " + discountstr
    adjsubstr = adjsub.to_s
    puts "adjusted subtotal = " + adjsubstr
  end
  puts "Order another? 1/2"
  @shit = gets.to_i
  if @shit != 1
    @shit = 2
  end
end

just pick one backend language you stupid niggar. no one cares how many languages you know, they want to see shit that you have made.
