Pointers in C — Part 2 Memory Diagram, Pointer Arithmetic, Arrays & Double Pointers Why DSA Needs C

Pointers in C — Part 2 | Memory Diagram, Pointer Arithmetic, Arrays & Double Pointers (Why DSA Needs Call-by-Reference) In this in-depth lecture (≈1 hour) we cover pointers at the memory level and how that knowledge powers Data Structures. This video includes clear memory diagrams, practical C code examples, and DSA use cases — perfect for B.Tech/BE students and placement preparation. What you’ll learn (timestamped): 00:00 Intro & goals 02:10 Memory model — bytes, addresses, and how variables are stored (visual diagram) 10:50 Pointer & array memory layout — contiguous storage and indexing internals 20:45 Pointer arithmetic — p+1, p+n, increments, pointer scaling explained (with examples) Call by value vs call by reference — mechanics & why C uses pointers for reference semantics Why DSA requires call by reference — linked list/insert/delete examples & function design Double pointers — definition, &pp, **pp usage, and practical examples Resources: • Full playlist (Data Structures in C): https://youtube.com/playlist?list=PLdGjQBvfMkuxUZeR4Y70o3KrW-8JNMbef&si=GIbe3CiCIrZ18ZmE • Download code & memory diagrams (GitHub): https://github.com/Kashif-Siddiqui-code/Data-Structures-in-C Recommended next videos: • Dynamic Memory Allocation • Structures in C, Self Referential Structures Timestamps help you jump to any subtopic — use them while revising.
