0.同一个符号、函数或对象在不同的场景下具有不同的作用效果
1.一是增加程序的灵活性，二是增加程序的可扩展性
2.可以
3.When I see a bird that walks like a duck and swims like a duck and quacks like a duck, I call that bird a duck.
4.低耦合

问答题：
0. 通过在类外定义使用类方法的函数。
1. 相同的函数，但可以面向不同的对象输出不同的结果。
2. 可以
3.
4. 降低耦合
5. 不属于

0,同一个函数在面对不同类型的对象能体现出相似但不同的功能
1,我认为主要是提高代码的简洁性,降低学习的难度
2.可以
3.
4.我认为是增强了内聚
5.不是,他只不过是利用了函数的基本特性
0.就这样吧
