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

C# (pronounced “C Sharp”) is an object-oriented, type-safe programming language developed by Microsoft, and is the primary programming language of the .NET framework. C# was originally designed to compete with Java, thus it shares many similarities in syntax and design principles. Origins and Development C# was born around the year 2000, aimed at building the … Read more
In C++, custom data types (such as classes and structures) can be used with operators (like +, -, *, <<, etc.) through operator overloading, enhancing the readability and usability of the code. Operator overloading is essentially function overloading, and thus must follow specific syntax and rules. Basic Syntax of Operator Overloading There are two forms … Read more
