What is the output of the following C++ code?

 

class A { public: A(int a = 4); void SetX(int a); int GetX(); virtual void print(); int x; private: }; A::A(int a ) { x = a; } void A::SetX(int a) { x = a; } int A::GetX() { return x; } void A::print() class B public A { public: B(int h 3); virtual void print (); int y; private: }; B::B(int h) { y h; { cout < < x < < endl; } A::SetX(h + 13); void B::print() { cout < < (*this).y + this->GetX() < < endl; } int main() { B bl, b2(2), *b3; A *data[4]; data[0] new B(4); data[1] = new A(5); bl.print(); b2.print(); b3 new B(3); data[2] = b3; data[0]->print(); data[1]->print(); data[2]->print(); return 0;
