Repeatedly Subtract Numbers

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

What is it you are trying to achieve?

I'm trying to find a way so that the user enters how many numbers they want to subtract, and then they can type the numbers (pressing Enter for each number). Finally, the result of subtracting all those numbers will be displayed. (Example: 6-3-3=0)


What is the problem you are having?

I have it in a loop, as it probably should be, but I can't seem to figure out a way to calculate any amount of numbers above 2...


Describe what you have tried to solve this problem

Again, I put them in a regular loop, with a counter to keep track & it is set to exit when it reaches the amount of numbers the user has said previously.


Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)

put "How many numbers would you like to subtract? " ..
        get exitwhen
        put ""
        if exitwhen = 2 then
                total := total - number2
            end if
            if counter = exitwhen then
                exit
            end if
            get number2
            total := number1 - number2

        end loop
        put ""
        put "The result of subtracting all ", exitwhen, " of your numbers is ", total, "!"

You're trying to use number2 inside the loop, but you don't actually get number2 until after the loop has executed. You can't use a variable before you've given it a value.

If you want to get number2 more than one time...maybe you should get it inside the loop?

Wait, maybe if I could find a way to keep the previous number that the user entered..?

Why do you need to keep the previous number? Once you've subtracted it, what else do you need it for?

Re: Repeatedly Subtract Numbers

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

Since I need to repeatedly subtract numbers entered by the user, I think it would be useful to keep updating the previous integer - how might I be able to do that, or possibly a different method that would do the same?  :?:

I think you might do well with one variable to hold the running total, and another to handle all input.
