The big problem that I am having is how to create the arrays (or arrays of pointers really) to dynamically assign memory at run time, to be able to collect the information from multiple selections ...

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

All array subscription operations in C get decomposed to pointer arithmetic anyhow; and when dealing with either multi-dimensional arrays or arrays of structs, where you want to access an ...

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 ...

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.
