Absolutely NOT! Without the [], C++ does not know that it's an array of
objects to be deleted instead of a single object, and the destructors would
not be called for elements 1..m of the array.

Your reference is outdated. Get Stroustrup's latest work, coauthored with
Margaret Ellis, The Annotated C++ Reference Manual, a.k.a. E&S.

< I don't know what delete [] m means.

As I said, your reference is outdated. The latest C++ rules say that the
number within the [] is unnecessary and the environment is required to keep
track of how many elements are in the array.
