Well, clearly you need to find out what value s has before you enter the loop, and why it might be larger than the number of elements.
We can't do that for you: you need the debugger to find out!

Value of s before entering loop was 1

Then look at the code using the debugger and see exactly what is happening each time it goes round the loop.
It's pretty obvious if you just pay attention to what you have written ... and the debugger would show that that immediately...

The index variable is I.

No, it's l

void oznaci_po_redu(int s)
{
l = 0;
while (s > 0)
{
l++;
if (!uzet[l]) s--; -----Index was outside the bounds of the array--------
}
uzet[l] = true;
}

But it gets increased while s is non zero, and when does s get reduced?

I changed this loop for (prog.u = 1; prog.u < 6; prog.u++) to for (prog.u = 0; prog.u < 5; prog.u++) now I have this error: imageshack.com/a/img923/8677/WIBoHG.png

Error is: Attempted to divide by zero.

Re: C# Numbers game

OriginalGriff17-Dec-16 4:37

Well, the error message pretty much explains itself.
Mathematics does not allow you to divide by zero, so you should probably make sure your application doesn't try to do that, wouldn't you say?

The fun bit is finding out why your application is trying at all. And - again - that's where you and Mr Debugger get to be good friends, because he's the one that tells you how the divisor came to be zero: which is pretty much essential to preventing it in future.

Seriously, get used to the debugger - it's a powerful, flexible tool that most developers spend a considerable amount of time with. It's a lot more fun - and a lot quicker - to find the information than it is to ask here. Especially as most of the time we have to say "use the debugger to get information" anyway! Laugh | :laugh:

When I changed all loops to start from 0 to n-1,those that start with other number than 0 I set to start from value reduced by 1 to n-1 I still get error: Index was outside the bounds of the array

I fixed that error but when I start program and input target value and values I get wrong expression.

When I type 100 for target number and numbers 5,8,9,4,20,50 for making expression I get:
5150-(' + w + ')+5355+5150

Instead of:
(6-1)*4*5

OK. Sit down and listen up.

Your'e trying to get everyone here to debug your code for you. That's not going to happen.

The debugger is there to debug YOU, to give you a tool to understands how your code works, what it's really doing, to increase your understanding.

USE IT.

The problem with the code you have is that you didn't write it and have no idea how it's supposed to work. This is where the debugger is an indispensable tool, to better your understanding of how the code works.

We can't do that for you.

if (!uzet[l]) s--; -----Index was outside the bounds of the array--------

This error message tells you that your code try to access an element rgat do not exist in the array uzet because uzet us too small.
With the debugger, check the size of uzet.

Hi, does someone know how to gain exclusive control of a human interface device input stream in c#? I have a keyboard and a magnetic stripe card reader and I don't want the card reader to write outside of my application and the keyboard to write inside.
Thanks
