Given the following class hierarchy in which each class defines a public default constructor and virtual destructor, which type name do the following statements print?

class A { /* .. . */};class B : public A { /* ... */};class C : public B { /* ... */};

(a) A *pa = new C;

cout << typeid(pa).name() << endl;

---

(b) C cobj;

A& ra = cobj;

cout << typeid(&ra).name() << endl;

---

(c) B *px = new B;

A& ra = *px;

cout << typeid(ra).name() << endl;
