Many beginners feel that learning C language becomes impossible halfway through, as they encounter several tough challenges that they cannot overcome. Consequently, many conclude that C language is too difficult and too close to the hardware level, especially those tough challenges that are hard to understand, making it difficult to proceed. Today, let’s discuss the … Read more
Introduction to Template Metaprogramming in C Language Template metaprogramming is a technique that combines programming with type systems, allowing computations to be performed at compile time. This approach can make programs more flexible and efficient. In C language, although there is no direct template mechanism, we can use macros and some techniques to achieve similar … Read more
Principles and Practice of Quick Sort Algorithm in C Language Quick sort is a highly efficient sorting algorithm widely used in various programming fields. It employs a divide-and-conquer approach, with an average time complexity of O(n log n). Let us explore the principles of quick sort and its implementation in C language. Basic Idea of … Read more

Do you know how the programming languages you often use are implemented? Today, let’s talk about this question. Smart humans discovered that by combining simple switches, they could express complex boolean logic. Based on this, they built the CPU, which can only understand switches in a simple way, represented numerically as 0 and 1. The … Read more
C++ Recursive Functions: Principles, Implementation, and Classic Cases Introduction Recursion is a common method in computer science, which is a programming technique where a function calls itself directly or indirectly. It is an effective and elegant way to solve problems, especially those that can be broken down into smaller sub-problems. In this article, we will … Read more
