person类，增加构造函数和析构函数，含拷贝构造函数。要求除了基本功能外，构造函数和析构函数中增加必要的输出信息。另增加一个函数参数为person对象的函数调用过程。-person class, increasing the constructor and destructor, including copy constructor. Requirements In addition to basic functions, constructors and destructors to inc

、声明一个CPU类，包含等级(rank)、频率(freauency)、电压(voltage)等属性，有两个公有成员函数run、stop。其中rank为枚举类型，声明为enum CPU_Rank { p1=1,p2,p3,p4,p5,p6,p7}，frequency为单位是MHz的整形数，voltage为浮点型的电压值。观察构造函数和析构函数的调用顺序。-creat a class CPU which includes rank frequency voltage . frequenc

在 C++ 里，如果我想让派生类的析构函数在释放内存时被调用，我得在基类中将其声明为虚拟函数。那么在 Visual Studio 2005 中，对于某个派生类来说，即使它在基类中未被声明为虚拟的，其析构也会被调用吗？-In C++ years, if I want a derived class destructor is called when the memory is released, I need to declare it as a base class virtual functi
