6-6 创建计算机 (10 分)
定义一个简单的Computer类，有数据成员芯片(cpu)、内存(ram)、光驱(cdrom)等等，有两个公有成员函数run、stop。cpu为CPU类的一个对象，ram为RAM类的一个对象，cdrom为CDROM类的一个对象，定义并实现这个类，为以上的类编写构造和析构函数，注意使用类组合的思想解决该问题，使得给出的主函数代码可以正确运行并得到给出的输出结果。
函数接口定义：
根据要求写出类的实现代码
裁判测试程序样例：
/* 请在这里填写答案 */
在这里给出函数被调用进行测试的例子。例如：
int main()
{
COMPUTER cpt1(6,4.0,200,60,32); //测试带参数构造
cout<<"cpt1's parameter:"<<endl;
cpt1.showinfo();
cout<<"------------------------------"<<endl;
COMPUTER cpt2; //测试不带参数构造
cout<<"cpt2's parameter:"<<endl;
cpt2.showinfo();
cout<<"------------------------------"<<endl;
COMPUTER cpt3(cpt1); //测试复制构造
cout<<"cpt3's parameter:"<<endl;
cpt3.showinfo();
cout<<"------------------------------"<<endl;
}
输入样例：
无
