华清远见嵌入式学习——C++——作业5

作业要求：

代码：

#include <iostream>using namespace std;//沙发 类
class Sofa
{
private:string sitting; //是否可坐double *cost; //花费
public://无参构造函数Sofa(){}//有参构造函数Sofa(string s,double c):sitting(s),cost(new double(c)){cout << "Sofa构造完成" << endl;}//拷贝构造函数Sofa(const Sofa &o):sitting(o.sitting),cost(o.cost){cout << "Sofa拷贝完成" << endl;}//析构函数~Sofa(){delete(cost);cost = nullptr;cout << "Sofa析构完成" << endl;}//拷贝赋值函数Sofa &operator=(const Sofa &o){if(this != &o){sitting = o.sitting;cost = o.cost;cout << "Sofa复制完成" << endl;}return *this;}//展示函数void show(){cout << sitting << " " << *cost << endl;}
};//床 类
class Bed
{
private:string sleep;int *size;public://无参构造函数Bed(){}//有参构造函数Bed(string s,int size):sleep(s),size(new int(size)){cout << "Bed构造完成" << endl;}//拷贝构造函数Bed(const Bed &o):sleep(o.sleep),size(o.size){cout << "Bed拷贝完成" << endl;}//析构函数~Bed(){delete(size);size = nullptr;cout << "Bed析构完成" << endl;}//拷贝赋值函数Bed &operator=(const Bed &o){if(this != &o){sleep = o.sleep;size = o.size;cout << "Bed复制完成" << endl;}return *this;}//展示函数void show(){cout << sleep << " " << *size << endl;}
};//沙发床 类  以公有继承方式继承于沙发和床
class Sofa_bed:public Sofa,public Bed
{
private:string color;
public://无参构造函数Sofa_bed(){}//有参构造函数Sofa_bed(string col, string sit, double cost,string sle,int size):Sofa(sit,cost),Bed(sle,size),color(col){cout << "Sofa_bed构造完成" << endl;}//拷贝构造函数Sofa_bed(const Sofa_bed &o):Sofa(o),Bed(o),color(o.color){cout << "Sofa_bed拷贝完成" << endl;}//析构函数~Sofa_bed(){cout << "Sofa_bed析构完成" << endl;}//拷贝赋值函数Sofa_bed &operator=(const Sofa_bed &o){if(this != &o){color = o.color;Sofa::operator=(o);Bed::operator=(o);cout << "Sofa_bed复制完成" << endl;}return *this;}//展示函数void show(){Sofa::show();Bed::show();cout << color << endl;}
};int main()
