[YTU]_2566( 虚基类练习：动物)

题目描述

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，包括动物(animal，属性有体长，体重和性别)，陆生动物(ter_animal，属性增加了奔跑速度)，水生动物(aqu_animal，属性增加了游泳速度)和两栖动物(amp_animal)。其中两栖动物保留了陆生动物和水生动物的属性。

输入

两栖动物的体长，体重，性别，游泳速度，奔跑速度(running_speed)

输出

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)
