  int x; 
  void showx() { cout << x << "\n"; } 
class BaseClass2 { 
  int y; 
  void showy() { cout << y << "\n"; } 
// Inherit multiple base classes. 
class DerivedClass: public BaseClass1, public BaseClass2 { 
  /* x and y are accessible because they are 
     protected in BaseClass1 and BaseClass2, not private. */

  ob.set(10, 20); // provided by DerivedClass 
  ob.showx();     // from BaseClass1
