In embedded system development, the C language dominates due to its proximity to hardware, efficiency, and portability. Although C is a procedural programming language, we can fully implement the core features of Object-Oriented Programming (OOP) through some programming techniques: encapsulation, inheritance, and polymorphism. Traditional C code has limitations, such as difficulty in managing global state, … Read more
In recent years, the Python programming language has become increasingly popular among programmers due to its simplicity and ease of learning and mastering. Additionally, it has a rich ecosystem of third-party libraries and well-developed management tools. From command execution to GUI programming, from B/S to C/S, from graphical techniques to scientific computing, software development to … Read more
Inheritance One of the important features of C++ is code reuse. Through the inheritance mechanism, new data types can be defined using existing data types. The new data type not only has the members of the old class but also has new members. Class B inherits from class A, also known as deriving class B … Read more
Inheritance 1. What is the concept? Inheritance is essentially an extension of an existing class’s characteristics, adding new functionalities. The new class created is called a derived class, while the class being inherited from is called the base class. In fact, inheritance is primarily a form of reuse at the class hierarchy level. For example, … Read more
Object-Oriented Programming – Classes Procedural Programming: A process-centered programming paradigm Object-Oriented Programming (OOP): A programming paradigm centered around objects Encapsulation, Inheritance, Polymorphism Basic Concepts of Classes and Objects A class encapsulates data and methods that share common characteristics, distinguishing them by access levels, to describe or abstract an entity Access levels in a class are: … Read more
11. Tuples and Sets In addition to lists and dictionaries, these two data structures are also very common: 1. Tuples (Immutable Sequences) Defined using <span>()</span>, once the elements are set, they cannot be modified (immutable) Suitable for storing fixed data (such as coordinates, configuration items) # Define a tuple point = (10, 20) # Coordinates … Read more
Common Use Cases of Python Magic Methods 1. Constructor and Initialization Methods 1. <span>__init__</span> – Initialization Method Function: Initializes attributes after the object is createdExample: class Person: def __init__(self, name, age): self.name = name self.age = age p = Person("Alice", 30) print(p.name) # Output: Alice 2. <span>__new__</span> – Instance Creation Method Function: Controls the object … Read more
The Essence of Object-Oriented Programming The core idea of Object-Oriented Programming (OOP) is to simulate concepts from the real world by creating custom data types, allowing data types to perfectly match the data being processed. This way of thinking makes the code more intuitive and easier to maintain. C++ Built-in Basic Types Integer Types #include … Read more
User-Defined Functions In C++ programming, although the standard library provides over 140 predefined functions, we often need to create our own functions in actual development. User-defined functions are one of the core concepts in C++ programming, especially in object-oriented programming and class design. Basic Concepts User-defined functions need to include the following elements: Function prototype … Read more
The concept of inheritance (literally, think of inheritance as in family assets) In Python, inheritance is a core concept of object-oriented programming, allowing a class (called a subclass) to inherit properties and methods from another class (called a superclass). This mechanism promotes code reuse, enhances code maintainability and scalability. Through inheritance, a subclass automatically acquires … Read more
