How make for loop with min max value ina Array

[Blokk]

You are a student, so learn:

We are not going to do your homework.

edit: First try to write down on a paper how you would do this task, if you have for example 4 numbers. You have to do < and > comparisons, I do not see anything like these in your block diagram.

First understand what you want to do, write a pseudo code:

I just need to know where in shift register is array[0] and array[1].

[Blokk]

that is the point 🙂 Nowhere 🙂 Did you try to understand what a shif register "does"? If you feed a value into the shift register (at the right side of the loop), the same value will "come out" and the NEXT iteration of your loop.

so how it works? i try to do something 5-6h and i have nothing. This is not to understand.

[Blokk]

Create this example VI, and turn on the "highlight execution" (little light bulb at the top of the block diagram). Study what kind of values you see "on" the wires, and appearing at the indicators during execution. The highlight execution slows down the code, so you can see how it works.

Edit: here are some links where you can learn LabVIEW:

Do some effort please...

Ok. now i understand in numeric i have last value, in numeric2 i have i-1(last value is i) in numeric3 is i-2 and in numeric4   i-3. But i dont understand why doesnt matter i enter "0", "30" or "100" in shift registers on left site in loop.

This is way too basic what you ask about, so even if I tell you something, you will not understand. You cannot learn LabVIEW in a few minutes. Do effort, and take first the tutorials...

I have this now, i know is bad, but maybe is closer? Maybe shift register is good?

Don't just randomly connect things without thinking first. Get code that is not broken and tweak it until you get the correct result.

How is the output array supposed to look like? Two elements, one the min and one the max in that order?

[crisdragon]

It can be two numeric indicators in output. All time i try everything but is not easy convert from C to VI.
