Tbh if you aren’t already using someone else’s array implementation that includes length information, just write your own simple wrapper e.g.

struct MyArrayWrapper { int *data; int length; }

At that point I would just use std::span if you can, then you also get the standard container/iterator interfaces for free.

The article did mention that that's what you'd probably have to do.

I have only one pointer (for example, if you created an array using new)

In most cases, it's necessary to rewrite the program a bit and add an array size passing. Sadly, that's how it works.
