Multiple Inheritance: What's a good example?

Question

I\'m trying to find a good example for the use of multiple inheritance what cannot be done with normal interfaces.

I think it\'s pretty hard to find such an example

Answer 1

The following is a classic:

class Animal {
 public:
  virtual void eat();
};

class Mammal : public Animal {
 public:
  virtual void breathe();
};

class WingedAnimal : public Animal {
 public:
  virtual void flap();
};

// A bat is a winged mammal
class Bat : public Mammal, public WingedAnimal {
};
