Help with...Lifelines in who wants to be..game

[McTam]

I can not figure out how to write the lifelines for my who wants to be a millionaire game....i have come a long way with the help of people from our beloved comp sci and it would be a shame if i couldn't figure this out so i can finish my program....
Can anyone help me with this part of my game?
fifty fifty-cancel two out of four answers for the question
ask the audience-since there is no audience....same as fifty fifty...
call a friend-give the answer for the question

Thanks guys.....I owe you HUGE!

well you have your list of possible choices. Now to do 50-50, you just create a new list of choices - 2 elements only. First add the correct answer. Then randomly pick another answer. Let the user chose from those two.

As for ask the audience - it is essensially the same, though I suggest also randomly generating some statistics. With a correct answer having a higher chance ofcourse

That sounds great! and the response time....astonishing....but.... ...
I can not write that in code is that a bother to ask for you to express yourself in computer language? Would love you for it! Thanks

I'm not sure how your questions are set up... lets assume the following

Turing:

var choice:array 1..4 of string choice[1] = "a" choice[2] = "b" choice[3] = "c" choice[4] = "d" var answerIndex:int := 2 % the answer is "b"      %// ofcourse all of the above should be loaded from a datafile

so we have an array full of answers and we know that 2nd one is correct.. aka choice(answerIndex)

now lets say we want to let the user pick just 2 of the above (after using 50-50)

Turing:

var wrongChoices:array 1..3 of int %all the wrong answers var myChoices:array 1..2 of int %1 correct 1 wrong var counter:int := 1 %just follow along for i:1..4      if i not= answerIndex then           wrongChoices(counter) := i           counter += 1      end if end for %now wrongChoices has all of the indexes but answerIndex %so myChoice(1) := answerIndex myChoices(2) := wrongChoices(Rand.Int(1,3)) %myChoice(1) is the correct answer's index %myChoice(2) is a random incorrect answer's index

and now you're ready! let the user pick between answer # myChoice(1) or myChoice(2).. you might want to keep track of the other two answers that will be crossed out, though those can be figured out since they are not in the list.

Turing:

loop      put "pick an answer"      get myAnswer      if myAnswer = myChoice(1) or myAnswer = myChoice(2) then           %check if myAnswer = answerIndex, if so - user wins            exit      else            put "what are you, stupid? you can't pick that"      end if end loop

hope that helps
