完成沙发床的多继承（有指针成员）

代码：

#include <iostream>using namespace std;class Bed
{
private:double *money;
public:Bed(){cout << "Bed::无参构造函数" << endl;}Bed(double money):money(new double(money)){cout << "Bed::有参构造函数" << endl;}Bed(const Bed &other):money(new double(*(other.money))){cout << "Bed::拷贝构造函数" << endl;}Bed &operator=(const Bed &other){if(this != &other){money = new double(*(other.money));}cout << "Bed::拷贝赋值函数" << endl;return *this;}~Bed(){delete(money);money = nullptr;cout << "Bed::析构函数" << endl;}void show(){cout << "money=" << *money << endl;}
};class Sofa
{
private:double *leight;
public:Sofa(){cout << "Sofa::无参构造函数" << endl;}Sofa(double leight):leight(new double(leight)){cout << "Sofa::有参构造函数" << endl;}Sofa(const Sofa &other):leight(new double(*(other.leight))){cout << "Sofa::拷贝构造函数" << endl;}Sofa &operator=(const Sofa &other){if(this != &other){leight = new double(*(other.leight));}cout << "Sofa::拷贝赋值函数" << endl;return *this;}~Sofa(){delete(leight);leight = nullptr;cout << "Sofa::析构函数" << endl;}void show(){cout << "leight=" << *leight << endl;}
};class BedSofa:public Bed,public Sofa
{
private:double *height;
public:BedSofa(){cout << "BedSofa::无参构造函数" << endl;}BedSofa(double money,double leight,double height):Bed(money),Sofa(leight),height(new double(height)){cout << "BedSofa::有参构造函数" << endl;}BedSofa(const BedSofa &other):Bed(other),Sofa(other),height(new double(*(other.height))){cout << "BedSofa::拷贝构造函数" << endl;}BedSofa &operator=(const BedSofa &other){if(this != &other){height = new double(*(other.height));Bed::operator=(other);Sofa::operator=(other);}cout << "BedSofa::拷贝赋值函数" << endl;return *this;}~BedSofa(){delete(height);height = nullptr;cout << "BedSofa::析构函数" << endl;}void show(){cout << "height=" << *height << endl;}
};int main()
{BedSofa s1(120,4,0.5);s1.Bed::show();s1.Sofa::show();s1.show();return 0;
}

运行结果：
