Summary  
The chapter explains how to define and use structs as custom composite data types for grouping related variables into a single unit, enabling the construction of complex hierarchical data structures.

General domain of usage  
Data modeling

A structure is a **set of variables** of different data types, united under one **common name**.

Definition

In other words, structures allow you to create **your own data types** that are cobbled together from other data types, for example:


One of the key benefits of using structures is the ability to create complex hierarchical data structures.
It is important to note that structures allow you to group variables that have a common context or relationship with each other. This allows programmers to logically organize data, making the code clearer and more readable.


Gain a solid understanding of how structs work in C, from basic definitions to advanced memory concepts. Explore how pointers interact with structured data, discover efficient ways to organize information, and build confidence by implementing real data structures such as linked lists.

Explore the fundamentals of structs, understand why they are used, and build confidence in defining, creating, and accessing structured data.

Discover how pointers interact with structs, learn why this connection matters, and master key techniques such as dynamic allocation and passing structs to functions

Gain a solid understanding of how structs are stored in memory, explore alignment and padding, and learn how unions help manage shared data efficiently.

Dive into advanced struct patterns, including nested and anonymous structs, explore practical ways to combine them with arrays, and get familiar with common data structures.

Build confidence by implementing a linked list from scratch, explore its structure, and create essential functions for adding, traversing, and managing list elements.
