When working with C, efficiency in memory usage can be a critical factor, especially in embedded systems or low-level programming. One lesser-known yet powerful GCC compiler flag that can help optimize storage is -fshort-enums. This flag changes the way the compiler allocates memory for enumerations (enum), potentially reducing the size of compiled code. In this […]
Using a single point of exit in C (or other programming languages) is often considered good practice because it improves code readability and maintainability, and reduces the likelihood of bugs. In this article, we’ll take a deep dive into this topic to see if it’s really true.
n the world of programming, writing secure and efficient code is a constant challenge, especially when working with low-level languages like C. C provides developers with powerful tools, but with great power comes great responsibility. Among these tools is the strlen function, a staple of string manipulation in C. While seemingly simple and straightforward, improper use of strlen can lead to unexpected behavior, performance issues, and even critical security vulnerabilities. This article explores the potential pitfalls of using strlen, why it’s considered unsafe in certain situations, and how developers can adopt safer practices to protect their applications.
