using arrays

-----------------------------------

hey guys, what i am doing is creating a multiple choice test. i have decided to use arrays for this. what i have going on right now is that i have an array for the questions, 0 to 14, and an array for the correct answers also 0 to 14. What i want is to have the choices to be in an array, but how do i make it display 4 at a time for just one index? if more info is needed i'll be glad to put it out.. i know this description isn't really great so just ask!

RE:using arrays

you can either use records, so that each index holds a custom type. Or your array can be 4 times as big, and you just keep in mind that index increments by four.

thanks for the help! i am not that good so how would i go about making the array four times as big and then using the increments of 4? wouldn't it just skip 3 and output the fourth?

tony said that you could do this


type ans:
    record
        question:string
        option :array 1..4 of string
        answer:int
        correctAnswer:int
    end record

var question:array 0..14 of ans

function poseQuestion (which:int):boolean
    put question(which).question
    for a:1..4
        put question(which).option(a)
    end for
    get question(which).answer
    if question(which).answer=question(which).correctAnswer then
        result true
    end if
    result false
end poseQuestion


question(0).question:="What colour is the sky???"
question(0).option(1):="1) Red"
question(0).option(2):="2) blue"
question(0).option(3):="3) green"
question(0).option(4):="4) none of the above"
question(0).correctAnswer:=2

put poseQuestion(0)
