Python functions are a fundamental concept in programming, allowing you to package code into a reusable tool that can be called by its function name. Imagine you have a series of repetitive tasks to perform every day, like making tea. The process of making tea includes boiling water, adding tea leaves, pouring water, and waiting … Read more
The ‘Mastermind’ Behind C++: A Deep Dive into the PIMPL Pattern Say goodbye to header file dependency hell, achieving true compilation isolation and ABI stability Introduction: Does your header file “say” too much? Hello, C++ developers. In C++, we are accustomed to placing class declarations in header files (<span>.h</span>/<span>.hpp</span>) and implementations in source files (<span>.cpp</span>). … Read more
Comprehensive Analysis of Procedure-Oriented and Object-Oriented C Programming: A Beginner’s Guide Introduction: The “Dual Identity” of C Language and the Core Differences in Programming Paradigms The C language is a native Procedure-Oriented Programming (POP) language—it lacks keywords such as class, object, and inheritance that are characteristic of Object-Oriented Programming (OOP). Its original design intent is … Read more
01 Class Design A class is the foundation of object-oriented design. A good class should have a single responsibility, a clear and concise interface, low coupling between classes, high cohesion within the class, and effectively demonstrate encapsulation, inheritance, polymorphism, and modularity.02 Single Responsibility of Classes Explanation: A class should have a single responsibility. If a … Read more
Encapsulation is the most core characteristic among the three major features of object-oriented programming. Encapsulation is the “integration” mentioned above (integration is an informal term, but it is relatively more vivid). The definition of encapsulation: hiding the attributes and implementation details of an object, only exposing interfaces to the outside, and controlling the access level … Read more
Click the blue text to follow us Introduction “Before the program runs, the thought comes first.” In the realm of computer science, C++ occupies an important position with its unique philosophical system. C++ is a powerful yet complex programming language designed by Bjarne Stroustrup[1](Figure 1), which supports multiple programming styles. It is not only an … Read more
1 Introduction to Function Macros Function macros are macro definitions that contain multiple statements, typically encapsulating frequently called functionalities without the overhead of stack operations associated with function calls. Function macros are essentially macros and can be defined directly, for example: #define INT_SWAP(a,b) \ int tmp = a; \ a = b; \ b = … Read more
Why should M and T be avoided in PLC programs? The core logic of programming standardization. 1. Fundamental Flaws of Global Variables In PLC programming, global variables such as M (memory relay) and T (timer) are widely used but have inherent weaknesses: unclear ownership and a scope that covers the entire program. The M and … Read more
When it comes to object-oriented programming, one might unconsciously think of C++ or Java. In fact, C language can also implement object-oriented programming. Object-oriented programming is a programming paradigm that is independent of the language tools used; some languages are just more suited for object-oriented programming. 1. Code Reusability and Layered Thinking What is code … Read more
Object-Oriented Programming vs. Procedural Programming Procedural Programming (POP): Focuses on functions, achieving program functionality through function calls. Data and functions are separate. For example, C is a typical procedural language. When developing a student grade management system, data structures are defined to store student information, followed by writing functions to implement adding, deleting, modifying, and … Read more
