Const, const pointers, and pointers to const things // combining const and const pointers can sometimes cause new C programmers some confusion. This video is here to help clarify things.


***

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.

The const keyword in C can be applied to variables and pointers in different ways. For simple variables, const can appear before or after the type ("west const" vs "east const"). With pointers, there are two distinct things you can make const: the pointer itself, or the data it points to. A "pointer to const int" means you can't change the value through dereferencing, but you can reassign the pointer. A "const pointer" means the pointer address can't change, but you can modify the pointed-to value. You can also combine both to create a const pointer to const data.
