array pupulating

[samjesse]

Hi

Please tell me why this code is reporting Array out of Range error? thx

   double temp[];
   temp[0] = 1.3;

And while at it. Does this language have the pop, push, ...etc for Arrays? I could not locate much help from the docs. Or hash or vectors or...etc...thx

Dynamic arrays should be initialized either with ArrayInitialize(), SetIndexBuffer(), or with CopyBuffer() (or its analogues).

As far as I know, pop, push, hash and vectors aren't supported in MQL5. But it looks like it's possible to write your own classes for this functionality. And, probably, such classes already exist somewhere.

what about the static arrays. do you still have to initialize them before populating them?

No. Just declare and use.
