Once again, pointers are simply memory addresses, and to fully utilize this similarity, C provides the concept of function pointers.

I have a bunch of hard-coded global 3D arrays of floats. I can loop through an individual 3D array just fine, but I also want to loop through all the 3D arrays. So, I thought of creating a one ...

For me, the four chapters that explain how to use pointers with functions, arrays, strings, and structures provide the most important information and examples for programmers and engineers. Chapter 7, ...

I’ve worked with a number of 8-bit embedded systems and their C compilers where using clearer expressions (e.g. arrays) produced worse binary code, and using stupid pointer tricks compiled to ...

Arrays are not pointers; pointers are not arrays. This is perhaps the most common misconception about C, and a “Guide to C Pointers” should not propagate it.
