public:

    cout << "Constructing base class\n"; 
    i = n;
  }
  ~BaseClass() { 
    cout << "Destructing base class\n"; 
  }
  void showi() { 
    cout << i << '\n'; 
  }
};

class DerivedClass : public BaseClass {
  int j;
public:

    cout << "Constructing DerivedClass class\n"; 
    j = n;
  }
