Advanced Data Types in C: Structures and Linked Lists

Writing efficient software requires a deep understanding of how data is organized and stored in system memory. In C, moving beyond basic variables to custom structures and dynamic memory is the key to writing professional-grade code. This text-based course guides you through the foundational concepts of structured data, pointer manipulation, and dynamic memory allocation. You will learn how to design custom data types, manage system memory safely, and implement fundamental data structures from scratch. What you will learn: Understand the fundamentals of structures, unions, and custom type definitions; Manage dynamic memory allocation safely using standard allocation functions while avoiding memory leaks; Build and manipulate dynamic linked lists to store and organize complex data sets; Apply modern C best practices for pointer safety, null-pointer checks, and structured programming; Create nested structures and pass them efficiently to functions using pointers. The course begins with essential definitions of structures and memory layouts before moving into pointer arithmetic and dynamic allocations. You will progress through step-by-step written explanations and clear code examples that demonstrate how to construct, traverse, and clean up linked lists. This course is designed for programmers who have a basic grasp of C syntax and want to transition to intermediate data management concepts. No advanced computer science background is required.
