Mixed array Examples and name

[Abhi1]

Hi can some one tell me if the below notations and their naming conventions are correct if wrong kindly please do provide an explanation.

a4 is not a regular 2D array. It is a Dynamic array of dynamic arrays. Each dynamic array can have a different size.

a4 = new[4];
foreach (a4[i]) a4[i] = new[i+1];

Also, use a datatype like int instead of $ when declaring an associative array. You cannot iterate when over the index $ because it has no type.

Hi @dave_59,

Are not the comments in the example wrong?
$ - is used for arrays which are queues.
* - is used for arrays which its index could be any integral expression.

SV queue (FROM SV LRM):

Associative arrays (From SV LRM):

So how come:

int a1[4][$];

Is a “Fixed array of associative array”, and not a “Fixed array of queues”?

[dave_59]

BTW, I saw the words “associative array” and mixed up $ for *.
Of course [$] is for queues and and [*] is a wildcard associative array. Sorry for the confusion.

So the $ in the quote above meant to be * ?

Correct, I should have said:

Also, use a datatype like [int] instead of [*] when declaring an associative array. You cannot iterate when over the index [*] because it has no type.
