No. Ada access types are very similar to C and C++ pointers, and are
typically implemented and used in (almost) exactly the same way.

I read

Well an access is not a pointer. System.Address is a pointer.  There
are
functions to convert an access to an Address..An access may contain
additional informations apart from the pointer - like size of the
object
pointed to (for indefinite objects), a reference counter (for access
all or
anonymous access) etc. pp. 

I think that not the same definition??
Can anybody tell me the exact difference between pointer in C++ and
access/address types in Ada???
