What is the true idea of object-oriented programming?The real idea of object-oriented programming is to forget everything about computers and consider problems in the field of problems,From question?My understanding:1. Abstract Th
1. The object
Object is one of the basic concepts of object-oriented programming, just look at the name and know it. In our familiar object-oriented language, such as Java or C + +, th
Object-oriented Programming (OOP) is a computer programming architecture. One of the basic tenets of OOP is that a computer program is composed of a single unit or object that can act as a subroutine. OOP achieves the three main goals of software engineering: reusability, fl

Basic Features
The three basic characteristics of object-oriented are encapsulation , inheritance , polymorphism. Package
The package is best understood. Encapsulation is one of the object-oriented features and is the main feature of object and class concepts.Encapsulation

Note:
1) Once the C ++ compiler finds that there are virtual functions in the class, it will generate a virtual function table for the class, add a pointer to the virtual function table in

Object-Oriented Programming, my thoughts
Preface:
This document aims to help my colleagues better understand object-oriented programming. This allows later users to take less detours, but many vulnerabilities and errors are inevit
in the previous example, we created the object through the constructor and wanted the object to inherit objects from another constructor.we can also directly target an object to achieve the purpose of inheritance, using subordinate steps:1.

The function super(Student, self) returns the parent class that is inherited by the current class, that is Person , then calls the __init__() method, notes that the self parameter is passed in super() , implicitly passes in, __init__() and
