C++ delete syntax -

I have come into this abnormal use of 'deletion'. Just wanted to know whether the following line removes both pointers or only the first?

Here the comma is a comma operator, not a separator. Only the first pointer, ptr1 has been removed.

The second indicator, ptr2 , is just one-none expression.

Delete has a higher preference than operator , operator, so the expression is written as written:

  (remove ptr1), (ptr2)

and not as it was written:

  delete (ptr1, ptr2)

If , to delete , then only the second pointer will be deleted.
