用C++来声明一个简单的Computer类

声明一个简单的Computer类，有数据成员cpu，ram，cdrom等有两个公有成员函数run()和stop()，其中cpu，ram和cdrom分别为CPU，RAM和CDROM的一个对象，定义并测试这个类。
本人急用的,谢谢~~

Answer 1

#include <iostream>
using namespace std;
class CPU;//关于这三个类的定义 ，相信你有
class RAM;
class CDRAM;
class Computer{
public:
void run();//具体的函数功能你自己设定
void stop();
private:
CPU cpu;
RAM ram;
CDROM cdrom;
};

Answer 2

class Computer{
public:
void start();
void end();
private:
HDD hdd;
CDROM cdrom;
CPU cpu;
};

Answer 3

C/C++ code
#include "iostream"
#include "string"
using namespace std;

class Client
{
public :

static void ChangeServerName(string strName)
{
ServerName = strName;
}

Client()
{
++ClientNum;
}

~Client()
{
--ClientNum;
}

static string ServerName;
static int ClientNum;
};

string Client::ServerName = "";
int Client::ClientNum = 0;

int main()
{
Client::ChangeServerName("server1");

Client* p1 = new Client;
Client* p2 = new Client;

cout<<"server name :"<<Client::ServerName<<endl;
cout<<"client num : "<<Client::ClientNum<<endl;

Client::ChangeServerName("server2");

delete p2;

cout<<"server name :"<<Client::ServerName<<endl;
cout<<"client num : "<<Client::ClientNum<<endl;

return 0;
}
