In this two-part tutorial we learn all about pointers and pointer-related bullshits. Part one focuses on the basics--the most common pointer operations and the basic underlying mechanisms. In part two, we take a look at some less commonly-used but still important pointer operations (pointer arithmetic), as well as some other concepts related to pointers. This tutorial introduces a lot of new concepts and features, but is light on practical examples. In the following tutorials we will get more hands-on practice with pointers, but also make sure to experiment with them on your own after finishing Tutorial 2.
