I think you're confusing two meanings of the word "object". The
one you're thinking of is taken from the phrase "object-oriented
programming". The other is that used by the C standard. From
C89 section 3.14:
object: A region of data storage in the execution
environment, the contents of which can represent values.
Except for bit-fields, objects are composed of contiguous
sequences of one or more bytes, the number, order, and
encoding of which are either explicitly specified or
implementation-defined. When referenced, an object may
be interpreted as having a particular type; see 22.214.171.124.
So in C (and, to some extent, C++), an object is just a region of
