how to do a for loop

[zmuccelmic]

Well I have a problem I don't know how to solve it.

The idea is simple but I have no idea how to implement it on LabView. Here it goes:

I start with an array a[i]. For i from 1 to 5 i initialize all values with zero. I want to build a for i from 1 to 5 loop that for each iteration replaces the i'th value of a[i] with i.

Maybe I'm missing something but I just don't know how to do it. I would appreciate it if you could give me some tips.

Welcome to LabVIEW.  You may want to spend some time learning about LabVIEW, it will make using it much easier.  A good place to start is the Learning Center at the Developer Zone.  You may also want to take a look at the free online courses offered here.

A for loop that is five indices long where each index holds the iteration number of the loop would look like this in LabVIEW:

 

 After re-reading your post I see that you want something slightly different than the solution above, but the example I showed you should be enough to get you going on the solution you are looking for.  Feel free to ask questions as they come up!

yeah...i know all this but i need to start with a predifined array then modify it. I don't want to build it.

You can initialize an array with the "Initialize Array" function, located in the palette at "Programming >> Array >> Initialize Array".

Is this what you are looking for?

This is what CMal is talking about:

Can be done this way.  Not sure why you need to initialize and then replace.  Much easier to just create using autoindexing.

 Memory Allocation? 🙂

If one needs to demonstrate how to initialize an array of a given size with a predetermined constant and then demonstrate how to replace values of that array, I suppose my way works.  Assignment?
