First, let me clarify a concept,bare programming, which refers to writing programs on bare metal. Bare metal, in the microcontroller field, refers to a microcontroller control system with hardware, so don’t get it twisted. Programming on bare metal is like cultivating a wasteland; every shovel that goes in will hit hard rocks. What’s the point … Read more
C++ is an efficient, flexible, and powerful programming language developed in the 1980s at Bell Labs based on the C language. It retains the efficiency and low-level control capabilities of C while introducing advanced features such as object-oriented programming, making it widely used in system development, game engines, embedded systems, and high-performance computing. Core Features … Read more

Below is a carefully planned C++ learning path to help you gradually … Read more
C++ is an efficient, flexible, and powerful programming language widely used in system development, game engines, high-performance computing, and more. It was developed by Bjarne Stroustrup in 1983 at Bell Labs, originally named “C with Classes,” aimed at extending the C language and introducing features of Object-Oriented Programming (OOP). 1. The Evolution of C++: A … Read more
Constructor 1. The compiler provides a default constructor only when no constructors are defined. If a constructor is defined and you want to use the default constructor, you must explicitly define the default constructor. 2. There can only be one default constructor, but multiple constructors can exist. 3. The default constructor can have no parameters; … Read more
In computer science, C and C++ are two very important and widely used programming languages. Although they share many similarities, there are also significant differences. This article will detail the relationship and differences between these two languages and provide code examples to help readers better understand. 1. Introduction to C C is a general-purpose, efficient, … Read more
Principles and Code Implementation of the Factory Pattern in Python The factory pattern is a design pattern for creating objects. It provides an interface for creating objects without specifying the exact class. The factory pattern helps us separate the creation of objects from their usage, thereby improving the flexibility and maintainability of the code. Basic … Read more
5. Object-Oriented Programming (OOP) 1. Classes and Objects python class Person: def __init__(self, name, age): # Constructor self.name = name self.age = age def say_hello(self): # Instance method print(f”Hello, I’m {self.name}, {self.age} years old.”) p = Person(“Alice”, 25) # Create an object p.say_hello() # Call method 2. Inheritance: A subclass inherits properties and methods from … Read more
