1477: 多重继承派生（1）--家具、床、沙发和沙发床

Description

家具类Furniture包含3个私有成员数据：家具类型（string type），家具主材料（string mat）和家具价格（int price）。成员函数包括构造函数（家具类型默认为unknown），三个获取私有成员数据的函数（GetType，GetMat，GetPrice）和输出家具类各成员数据函数show（输出格式详见Sample Output）。

床类Bed由Furniture类公有派生而来，包含1个私有成员数据：床类型（string bedtype）。成员函数包括构造函数（家具类型默认为“床”），获取私有成员数据床类型的函数GetBedType和输出床的各成员数据值的函数Show（输出格式详见Sample Output）。

沙发类Sofa由Furniture类公有派生而来，包含1个私有成员数据：座位数（int seats）。成员函数包括构造函数（家具类型默认为“沙发”），获取私有成员数据座位数的函数GetSeats和输出沙发的各成员数据值的函数Show（输出格式详见Sample Output）。

沙发床类SofaBed由Sofa类和Bed类公有派生，包含2个成员函数：构造函数（家具类型默认为“沙发床”），输出沙发床的各成员数据值的函数Show（输出格式详见Sample Output）。

完成上述各类的设计。main函数已给定（如下所示），提交时只需要提交main函数外的代码部分。

int main()

{

string mat,bedtype;

int price,seats,cas=0;

while(cin>>mat>>price>>bedtype>>seats)

{

cas++;

cout<<"Case #"<<cas<<":"<<endl;

Furniture furniture(mat,price);

Bed bed(bedtype,mat,price);

Sofa sofa(seats,mat,price);

SofaBed sofabed(seats,bedtype,mat,price);

cout<<"Furniture:"; furniture.Show();

cout<<"Bed:"; bed.Show();

cout<<"Sofa:"; sofa.Show();

cout<<"SofaBed:"; sofabed.Show();

}

return 0;

}

Input

包含多组数据（数据均正确合法）

每组测试数据1行，每行包含4个数据，第一个数据是字符串（表示家具主材料），第二个是整数（表示家具价格），第三个数据是字符串（表示床的类型），第4个数据是整数（表示座位数）。

Output

每组测试数据输出具体格式详见Sample Output。
