Description

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。

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)

Sample Input

5222f102122

Sample Output

HINT

前置代码及类型定义已给定如下，提交时不需要包含，会自动添加到程序前部

/*C++代码*/

#include <iostream>

using namespace std;

class animal

{

protected:

    int height;  //身高或体长

    int weight;  //体重

    char sex;   //性别

public:

    animal(){}

    animal(int h,int w,char s):

        height(h),weight(w),sex(s){}

};

class aqu_animal:virtual public animal  //水生动物

{

protected:

    int swimming_speed;  //游泳速度

public:

    aqu_animal(){}

    aqu_animal(int h,int w,char s,int s_p):

        animal(h,w,s),swimming_speed(s_p){}

};

主函数已给定如下，提交时不需要包含，会自动添加到程序尾部



/*C++代码*/

int main()

{

    amp_animal a1(50,20,'m',100,120);

    amp_animal a2;

    a2.input();

    a1.show();

    cout<<endl;

    a2.show();

    return 0;

}
