Description
Tom家里养了很多动物,比如有鸭子、火鸡和公鸡。它们的叫声都不相同。现在,请编写类Animal、Cock、Turkey和Duck,根据给出的main()函数及样例分析每个类的属性、行为及相互关系,以模仿Tom家的情况。
提示:动物们都有自己的名字。
Input
输入有多行。第一行正整数M表示之后有M个测试用例,每个测试用例包括2部分:前一部分是动物的名字,后一部分是动物的类型(用A、B、C分别表示鸭子、火鸡和公鸡)。
Output
输出有M行,每个测试用例对应一样。见样例。
Sample Input
3 Baby C Rubby B Tobby A
Sample Output
Baby is a cock, and it can crow. Rubby is a turkey, and it can gobble. Tobby is a duck, and it can quack.
