create an array without entering the size in the new[] statement

Question

By mistake i forgot to enter the size of the array and wrote something like

int* ptr = new int[];

I was surprised when the code compiled. So, now since it compiled; could anyone let me know what is the meaning of this? it is creating an array of size?

What compiler? I don't think it is standard. – Robert Prévost Nov 18 '16 at 03:58 — Robert Prévost, Nov 18 '16 at 03:58

As far as I can tell from looking at the disassembly, this is just a non-standard way of saying int* ptr = new int[0]; (see here for what that means).
