Reference: http://www.weixueyuan.net/view/6373.htmlSummarize:A constructor cannot be declared as a virtual function, and a destructor can be declared as a virtual function.After the destructor of the base class is declared as a virtual function, the

Declare the destructor of the polymorphism base class as a virtual function. Now we want to consider a timer problem. First we create a base class named timekeeper, and then create various derived classes based on it, so that we can use different

Constructor: C ++ provides constructor to process object initialization. It is automatically executed when an object is created. The name of the constructor must be the same as the class name. It does not have any type or return any value. The

C + + clearly states: when the derived class object is deleted by a base class pointer, and the base class takes a non-virtual destructor, the result is undefined-- The actual execution usually occurs when the derived component of the object is not

1. Why do I need to define a virtual destructor? If oneClass with the virtual function, it needs a virtual destructorFor the following reasons:1) if a class has a virtual function, it is often used as a base class;2) if it is a base class, Its
