Unit IV – Pointers & Structures

Learn how pointers, memory, structures, and functions work together to build efficient and powerful C programs.

Unit Summary

This unit introduces powerful concepts in C, including pointer manipulation, memory handling, structured data using structs and unions, and the integration of functions with these elements. These topics form the backbone of efficient system-level programming.
