• Using pointers with structs, arrays, and functions

Pointers are the first real hurdle to a deeper understanding of C. They are used in contexts where we have to be able to access objects from different points in the code, or where data is structured dynamically on the fly.

The confusion of inexperienced programmers between pointers and arrays is notorious, so be warned that you might encounter difficulties in getting the terms correct. On the other hand, pointers are one of the most important features of C. They are a big plus to help us abstract from the bits and odds of a particular platform and enable us to write portable code.
