11.6.5.dynamic_cast: Cast from Derived * to Derived *
#include <iostream>
using namespace std;

class Base {
public:
  virtual void f() {
     cout << "Inside Base\n";
  }
};

class Derived : public Base {
public:
  void f() {
     cout << "Inside Derived\n";
  }
};

int main()
{
  Base *bp, b_ob;
  Derived *dp, d_ob;

  dp = dynamic_cast<Derived *> (&d_ob);
  if(dp) {
    cout << "Cast from Derived * to Derived * OK.\n";
    dp->f();
  else
    cout << "Error\n";

  cout << endl;

  return 0;
}
Cast from Derived * to Derived * OK.
