Continuing from the previous article, after understanding class definitions and function definitions, we begin to learn about object-oriented programming, which has three main characteristics: encapsulation, inheritance, and polymorphism. Let’s learn about each of these: 🔒 Characteristic 1: Encapsulation The core idea: encapsulating data and methods together, hiding internal implementation details Detailed case: ATM machine class … Read more
If you are just learning Python, are you still writing a bunch of messy functions? When you encounter repeated functionalities, do you copy and paste, and when you modify the code, does it affect everything? In fact, there is a more efficient programming method in Python—Object-Oriented Programming (OOP). It is like “bringing” real-world objects into … Read more
AbstractAbstract: The teaching of classical Chinese literature has long faced the dilemma of focusing on word translation while neglecting the text’s meaning, emphasizing knowledge transmission over the cultivation of thinking. “There are fish in the North Sea” is a classic opening text of “Zhuangzi: The Happy Wanderer,” serving as a core text that embodies Zhuangzi’s … Read more

Original Book Cover: Guideline 6: Adhere to the Expected Behavior of Abstractions (Guideline 6: Follow the Expected Behavior of Abstractions) Reading Notes: 1. Explanation • Good abstract design should not establish inheritance relationships solely based on “what it is” but should judge based on “whether the behavior is consistent”. Subclasses must be able to seamlessly … Read more
In complex embedded systems (such as multi-device driver frameworks, protocol stacks, state machines), good code organization is often required. By using structures and function pointers, we can simulate the three main characteristics of object-oriented programming in C language: Encapsulation, Inheritance, and Polymorphism. Implementation of Object-Oriented Concepts in C Encapsulation Principle: Encapsulate data and operations on … Read more
As a professional in the surveying industry, merely using surveying instruments for measurement and software for drawing is far from sufficient. For instance, to process a batch of surveying data, one needs to understand programming to utilize computers for batch processing.Additionally, developing an internal data processing software also requires programming skills. Furthermore, modern three-dimensional urban … Read more
1. In Python, a class is a template for creating objects, defining the common attributes (data) and methods (behavior) of the objects; an object is an instance of a class, a concrete implementation of the class.The relationship between classes and objects: a class is like a blueprint for a car, specifying that the car should … Read more
In C++ Object-Oriented Programming (OOP), classes, inheritance, and composition are the three pillars for building complex programs. They not only help us achieve code reuse but also make the program structure clear and easy to maintain. Today, we will thoroughly understand these three core concepts from theory to practice. 1. Classes: The “Basic Unit” of … Read more
