I can't figure out why the use of Virtual in the C++ code below does not solve my problem of multiple inheritance:

#include <iostream>

using namespace std;

class LivingThing {

public:

  void breathe() {

    std::cout << "I'm breathing as a living thing." << std::endl;

  }

};

class Animal : virtual public LivingThing {

public:

  void breathe() {

    std::cout << "I'm breathing as an animal." << std::endl;

  }

};

class Reptile : virtual public LivingThing {

public:

  void breathe() {

    std::cout << "I'm breathing as a reptile." << std::endl;

  }

  void crawl() {

    std::cout << "I'm crawling as a reptile." << std::endl;

  }

};

class Snake : public Animal, public Reptile {

};

int main() {

  Snake snake;

  snake.breathe();

  snake.crawl();

  return 0;

}
