Square brackets

#1

I know it’s a trivial question now, but this syntax I found in some patches:
kArr2[kMaxIndx] = 0
What does it correspond to mathematically? What is the effect of the square brackets in this case?
Thanks for any answer!

#2

Good question. These refer to the fact that kArr2 is a k-rate array. Meaning it holds a list of numbers. The paramrter passed within the square brackets indicates which number from the kArr2 list to access. It’s not that different from accessing a value from a function table. You can read more about arrays in Csound here.

Feel free to ask further questions if you have any. :slight_smile:

Thanks Rory,

I am also deepening the topic on the text by Lazzarini (and other authors) “Csound”.

Well, indeed this tool can become a valuable resource…

I was also wondering how to represent this line of code with a flowchart:
kArr2[] init gitable

And also this other one:

kArr2[kMaxIndx] = 0

That’s a good question. I’m not really sure how best to show arrays in flowcharts. I guess there has to be some kind of general approach? But I’ve no idea. Maybe something like this?

Of course, it could be a way to graphically represent the array… :+1:
