How to find the range of integers

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

What is it you are trying to achieve?

I am trying to write a program that can take any series of positive integers and output the range from smallest to largest.

What is the problem you are having?

How can I find the range when I do not know how many integers the user will enter?

Please specify what version of Turing you are using

4.1.1

You don't need to store all of the integers. You just need to remember the largest and the smallest you have seen so far.

This is what I have so far. Is there a way that I can declare minint as something other than the largest value that Turing will allow the user to input (10000000)?

var minint, maxint, integer : int
maxint := 0
minint := 10000000

loop
    put "Enter an integer."
    get integer
    if integer < 0 then
        exit
        elsif integer > maxint then
            maxint := integer
        elsif integer < minint then
            minint := integer
        end if
    end loop

    put "The range of the previous integers is ", maxint - minint, "."

RE:How to find the range of integers

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

There are a few options. You could set the initial value to the maximum value you can store in an integer: http://compsci.ca/holtsoft/doc/maxint.html . You could also notice that your problem only requires you to handle positive integers -- so what could you do to store a value that means "not yet assigned" to your maxint value?

Okay I set the initial value to maxint, thank you so much! :)
