<p>
The special identifiers <tt>final</tt> and <tt>override</tt> can be used on methods and destructors,
such as in the following example:
</p>
<div class="code"><pre>
struct BaseStruct {
virtual void ab() const = 0;
virtual void cd();
virtual void ef();
virtual ~BaseStruct();
};
struct DerivedStruct : BaseStruct {
virtual void ab() const override;
virtual void cd() final;
virtual void ef() final override;
virtual ~DerivedStruct() override;
};
