Try with

void Finder_i::find (short &i)
	{
		cout << i;
	}

You need to tell the compiler that it's a member function of the
Finder_i class that you're implementing, not a global function.

By the way, I guess your function is called "Find" rather than "find";
that what the compiler thinks, at least.
