So - next let's examine a rather simple declaration of an array in C/C++.

  int arr[5];

What does this define.

This defines a contiguous set of 5 `int' elements.  The name of that set
is 'arr'.  

What is the type of 'arr'?  It is an array of 5 'int' elements.

What is 'arr'?  

'arr' represents, at execution time, a set of 5 contigous 'int' 
elements.  The name 'arr'
is used to refer to the runtime location of that set of elements.  We 
can colloquially
use the term, the "address" of the set of 5 contiguous 'int' elements 
when we talk
about the runtime location of the set of 5 contiguous 'int' elements.

That is, the name 'arr' refers to the runtime location (or "address") of 
the set
of 5 contiguous 'int' elements.

Does that sound right so far?
