Understanding the if Statement: A Deep Dive into C Language Control Structures In programming, control flow refers to a series of statements that determine the order of execution of a program. The <span>if</span> statement is one of the most fundamental and commonly used control structures in C language. It allows us to execute different blocks … Read more
Graphical User Interface: Basics of C Language GUI Programming A graphical user interface (GUI) is the standard interaction method for modern applications, allowing users to interact with programs through images and visual indicators rather than relying solely on text commands. While many developers prefer to use higher-level languages for GUI programming, such as Python or … Read more
Applications and Examples of Signal Handling in C Language Signal handling is an important concept in operating systems and programming, especially in C language, as it allows programs to respond to asynchronous events such as user input, timer expirations, or signals from other external devices. In this article, we will explore the basic principles of … Read more
Real-Time Requirements in Embedded C Programming In embedded systems, real-time is a crucial concept. Whether it is controlling motors, collecting sensor data, or handling communication protocols, tasks must be executed within strict time constraints. This article will detail the real-time requirements in embedded C programming and provide relevant code demonstrations. What is Real-Time? Real-time refers … Read more
C Language For Loop: Efficient Iteration Programming Techniques In C language, <span>for</span> loop is a very commonly used control structure that allows us to repeatedly execute a block of code under a specific condition. Compared to other loop structures like <span>while</span> and <span>do…while</span>, the <span>for</span> loop is usually more concise and readable, making it particularly … Read more

This is a short document describing the preferred coding style for the Linux kernel. Coding style is very personal, and I won’t force my views on anybody, but this is what goes for anything that I have to be able to maintain, and I’d prefer it for most other things too. Please at least consider … Read more
