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.

#include<iostream> using namespace std; class Animal{ protected: string n; public: Animal(){} Animal(string name):n(name){} void sound(){} }; class Cock:public Animal{ protected: string n; public: Cock(string name):n(name){cout<<n<<" is a cock, and it can crow."<<endl;} void sound(){cout<<n<<" is a cock, and it can crow."<<endl;} }; class Turkey:public Animal{ protected: string n; public: Turkey(string name):n(name){cout<<n<<" is a turkey, and it can gobble."<<endl;} void sound(){cout<<n<<" is a turkey, and it can gobble."<<endl;} }; class Duck:public Animal{ protected: string n; public: Duck(string name):n(name){cout<<n<<" is a duck, and it can quack."<<endl;} void sound(){cout<<n<<" is a duck, and it can quack."<<endl;} }; int main() { int cases; string name; char type; Animal *animal; cin>>cases; for (int i = 0; i < cases; i++) { cin>>name>>type; switch(type) { case 'A': animal = new Duck(name); break; case 'B': animal = new Turkey(name); break; case 'C': animal = new Cock(name); break; } animal->sound(); } return 0; }
