Click the blue text Follow the blogger 1. Background Since the early 21st century, there has been talk of the impending end of the C++ language. Especially with the explosion of the internet economy and enterprise applications, new programming languages such as Java, C#, Python, Go, and Rust have quickly captured the market with their … Read more
Have you ever wondered how that cup of Luckin coffee you order every morning is still served in order, even when dozens of people are placing orders at the same time? Or how the 12306 ticketing system handles thousands of concurrent requests while still ensuring first-come, first-served? The answer is simple: Queue. Today, we are … Read more
Although the principles of structured programming improve the clarity, reliability, and maintainability of programs, they still face challenges when writing large programs. To address these challenges, Object-Oriented Programming (OOP) offers a new approach. Unlike procedural programming, which emphasizes algorithms, OOP emphasizes data. OOP does not attempt to make problems fit the procedural approach of the … Read more

Boost.Integer: A Powerful Integer Library in C++ Boost.Integer is a significant component of the Boost C++ library collection, providing robust support for integer types, particularly useful in generic programming. Boost.Integer offers a range of tools to help developers select the appropriate integer type based on characteristics such as bit width, maximum value, and more, while … Read more
C++ generic programming is a powerful programming paradigm that allows you to write code that is independent of specific data types, thereby enhancing code reusability and flexibility. What is Generic Programming? The core idea of generic programming is “write once, use many times”. It enables functions or classes to handle multiple data types without the … Read more
Before C++11, variable definitions had to explicitly specify types—whether it was a<span><span>int</span></span>, or a<span><span>std::vector<int>::iterator</span></span>, both simple and complex types required manual declaration by the developer.This not only made the code verbose (especially in generic programming) but also increased maintenance costs.To address this issue, C++11 introduced the <span><span>auto</span></span> and <span><span>decltype</span></span> keywords, enabling compile-time automatic type deduction.This … 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
Generic Programming in Python: Practical Insights on Generic Types The demand for implementing static type constraints in dynamic type languages has fostered the development of generic programming in Python. Generic programming allows developers to write reusable, type-safe code while maintaining the flexibility of Python. Python enhances its type hinting system with generic support through tools … Read more
As a C language developer, have you ever faced the problem of needing to implement a generic linked list, only to find that you must write the code separately for each data type? Or designing a callback function but not knowing how to handle various types of parameters? The root of these issues lies in … Read more
