虚基类练习 动物1

Posted 2020-09-12 clnchanpin

/*长期的物种进化使两栖动物既能活跃在陆地上，又能游动于水中。

利用虚基类建立一个类的多重继承。包含动物(animal，属性有体长，体重和性别)，
陆生动物(ter_animal，属性添加了奔跑速度)。水生动物(aqu_animal。
属性添加了游泳速度)和两栖动物(amp_animal)。
当中两栖动物保留了陆生动物和水生动物的属性。
Input
两栖动物的体长，体重。性别，游泳速度，奔跑速度(running_speed)
Output
初始化的两栖动物的体长，体重，性别，游泳速度。奔跑速度(running_speed)
和输入的两栖动物的体长，体重。性别。游泳速度，奔跑速度(running_speed)*/
