定义一个房间类（ CRoom )，要求拥有的私有数据成员：门牌号（ m _ id )，门( m _ pdoor )，窗户（ m _ window )。其中，门是门类（ CDoor ）定义的对象指针成员，窗户是窗户类（ CWindow ）定义的对象成员。要求：每个类单独定义在两个文件中（. h 和． cpp )，房间类包括：构造函数、析构函数， InstallDoor 成员函数能够实现安装门（ new CDoor ）的功能。要求窗户类的构造函数必须带参数， CDoor 类具有宽度，高度及修改宽度高度功能◇ CWindow 类具有宽度，高度及修改宽度高度功能。设计好后测试。C++

测试代码：

#include <iostream>
#include "CRoom.h"

using namespace std;

int main() {
    CRoom room1(101);
    room1.InstallDoor(1.2, 2.1);
    cout << "Door width: " << room1.m_pdoor->GetWidth() << ", height: " << room1.m_pdoor->GetHeight() << endl;
    room1.m_pdoor->SetWidth(1.5);
    room1.m_pdoor->SetHeight(2.3);
    cout << "Door width: " << room1.m_pdoor->GetWidth() << ", height: " << room1.m_pdoor->GetHeight() << endl;
    return 0;
