Stream 13 — C for Red Teaming (Part 4): Arrays, Functions & Structures

“We shape data into meaning — and then teach machines to obey. Tonight we learn the forms that hold systems together.”

Tonight we continue our live journey into C for Red Teaming — Part 4.
We’ll dig into the building blocks that let us model, manipulate, and reason about memory and data: arrays, functions, and structures — the quiet architectures behind tools, exploits, and defensive fixes.

🔎 What you’ll learn tonight

Arrays: memory layout, indexing, multi-dimensional arrays, common pitfalls (and how to avoid them)

Functions: prototypes, scope, passing by value vs pointer, stack frames and why they matter for security

Structures: designing C structs, memory alignment, padding, and using structs safely in network and file I/O

Live demos: small, safe programs compiled on Kali, gdb introspection of stack & heap, and defensive fixes for common mistakes

🧩 Why this matters for red teaming

Understanding how arrays, functions, and structs are represented in memory gives you the power to:

read and reason about binaries and network packets

write robust security tools and parsers

understand where vulnerabilities hide (so you can responsibly find and fix them)

Ethics & safety: All demos are educational and run on local, intentionally vulnerable test programs. We do not exploit public systems. Red teaming is about knowledge + permission.
