Pointers: Basics and Applications

This lecture covers the fundamentals of pointers in C, including binary, decimal, and hexadecimal number systems, unary operators, memory management, pointer types, initialization, accessing variables indirectly, pointer arithmetic, structures, functions, and arrays. The instructor explains how pointers enable functions to modify variables, the importance of passing arguments by value, and how pointers help reduce memory footprint. Examples illustrate how to work with pointers to access data indirectly, modify variables, and efficiently handle arrays. The lecture also delves into pointer arithmetic, protecting function arguments, and passing arrays to functions.
