Defining Constants. Should I use CONST or #DEFINE? // Just a quick video about constants. A lot of you have asked whether it's better to use preprocessor macros (#define) or const variables when defining your program constants. Both are acceptable, but they're not the same. This video breaks down some of the differences.

Welcome! I post videos that help you learn to program and become a more confident software developer. I cover beginner-to-advanced systems topics ranging from network programming, threads, processes, operating systems, embedded systems and others. My goal is to help you get under-the-hood and better understand how computers work and how you can use them to become stronger students and more capable professional developers.


About me: I'm a computer scientist, electrical engineer, researcher, and teacher. I specialize in embedded systems, mobile computing, sensor networks, and the Internet of Things. I teach systems and networking courses at Clemson University, where I also lead the PERSIST research lab.
