Declaration or Definition

Question

Is this, line of code that is presented below and under this sentence, considered a declaration or definition?

extern const int &ri;

Answer 1

It's a declaration- the "extern" means that it lives somewhere else.

Answer 2

C++03, §3.1, ¶2:

A declaration is a definition unless ... it contains the extern specifier or a linkage- specification and neither an initializer nor a function-body ...

So, extern const int &ri;, which contains the extern specifier and not an initializer is a declaration but not a definition.
