This document discusses pointers in C including pointer to arrays, pointers with unknown types, passing pointers by reference, pointers to pointers, NULL and unassigned pointers, pointers to functions, pointer tricks with operator precedence and associativity, reading bytes from data streams, pointers with constants, and modularity. The document is authored by ENG. Keroles Shenouda and provides a link to a Facebook group on embedded systems.
