Example: virtual function c++

class Entity {
public:
virtual std::string getName();
void print();
};
virtual std::string Entity::getName() {
return "Entity";
}
void Entity::print() {
std::cout << "This is the base class" << std::endl;
}
class Player : public Entity {
std::string m_name;
public:
Player(const std::string& name): m_name(name) {};
void print();
virtual std::string getName();
};
virtual std::string Player::getName() {
return m_name;
}
void Player::print() {
std::cout << "This is the sub class" << std::endl;
}
int main() {
Entity* e = new Entity();
std::cout << e->getName() << std::endl;
Player* p = new Player("Jacob");
std::cout << p->getName() << std::endl;
p->print();
e->print();
Entity* notVirtualEntity = new Entity();
Player* notVirtualPlayer = new Player("Bob");
notVirtualEntity = notVirtualPlayer;
notVirtualEntity->print();
notVirtualEntity->getName();
}
