What will the following program display?

#include <iostream>

using namespace std;

class First

{

protected:

  int a:

  public:

  First(int x = 1)

  { a = x; }

  virtual void twist()

  { a * = 2; }

  int getVal ()

  { twist(); return a; }

}:

class Second : public First

{

private:

  int b:

  public:

  Second(int y = 5)

  { b = y; }

  virtual void twist()

  { b *= 10: }

};

int main()

{

First object^-1;

Second object2;

cout ≪ object1.getVal () ≪ endl;

cout ≪ object2.getVal() ≪ endl;

return 0;
