What is the output of the following main()? Suppose the code segments will be assembled and embedded correctly in a C++ program.

CODE:

class small

{

public:

void print() const { std::cout << "small: x " << x << ", y " << y << " "; }

int add() { return x + y; }

small(int a = 0, int b = 0) : x(a), y(b) {}

private:

int x;

int y;

};

class notSmall : public small

{

public:

void print() const { small::print(); std::cout << "notSmall: z " << z << " "; }

int add() { return small::add() + z; }

notSmall(int a = 0, int b = 0, int c = 0) : small(a, b), z(c) {}

private:

int z;

};

int main()

{

small * ptrSmall;

small objSmall(2, 3);

notSmall objBig(3, 5, 7);

ptrSmall = &objSmall;

std::cout << ptrSmall->add() << " ";

ptrSmall->print();

ptrSmall = &objBig;

std::cout << ptrSmall->add() << " ";

ptrSmall->print();

return 0;

} // end main

What would be the output of the main()in a, if the print() and add() of class small are virtual functions?
