    Is that sample code correctly?

    Could you say me is that code fully correctly?

    A Fun()
    {
    A a = 0;
    return a;
    }

    const A& a = Fun();
    A b = a;

    to say it's "fully" correct, you should show us the definition of A ...

    anyway, supposing that A is non-explictly constructible from an int and that it is also copy constructible, it's correct.

    if you have doubts about the line "const A& a = Fun();", note that a temporary bound to a const reference will survive up to the end of the scope in which the reference is defined; so, again, it's ok.
