What this article shares with you is about what to achieve dynamic polymorphism. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Let's take a look at it with the editor.

What does dynamic polymorphism mean? -- also known as run-time polymorphism, means that zhi determines which class's member function is called this time when the program is running.

How to realize dynamic polymorphism--

(1) the base class declares that those subclasses will have their own version of member functions as virtual functions.

(2) subclass redefines the virtual function declared by the base class

(3) in the application, the base class pointer (or reference) is used to point to the object of the relevant class, and the member function is called with that pointer (or reference).

The above is what to achieve dynamic polymorphism, the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
