下面代码中 v1、v2 调用相同接口 move() 但输出不同，体现了面向对象的（ ）特性。
class Vehicle { ... virtual void move() const { ... } };
class Car : public Vehicle { void move() const override { ... } };
class Bike : public Vehicle { void move() const override { ... } };
Vehicle* v1 = new Car("Toyota", 5);
Vehicle* v2 = new Bike("Giant");
v1->move(); v2->move();
