Re: Class casting

Interestingly enough, if you did this:

int main() {
        B b;
        C* c = new C(b);
}

It will compile and work as expected. The constructor wants an A, a B is
an A, so everything is fine.

Why one needs to declare the B first, rather than instantiating the
temporary as in the code below, I have no idea. Can anyone shed some
light on this?
