C Programming & Low-Level Concepts

Course Overview

Gain a deep, unvarnished understanding of computer architecture, execution mechanics, and low-level system programming using C. This course explores modern software execution down to the hardware level, covering explicit memory allocation, direct pointer arithmetic, bitwise manipulation, and dynamic data structures. Learn how to write high-performance, memory-efficient software and debug low-level hardware interactions with confidence.

Key Learning Outcomes

• Understand C programming syntax, control structures, custom functions, and compilation lifecycles (GCC/Clang).
• Master pointer mechanics, memory address spaces, stack vs heap allocation, and dynamic memory functions (`malloc`/`free`).
• Implement low-level custom data structures including linked lists, stacks, queues, hash maps, and binary trees from scratch.
• Debug memory leaks, segmentation faults, and buffer overflows using tools like Valgrind and GDB.

Detailed Syllabus

• Module 1: Core C Fundamentals & Compilation: Variables, data types, operators, preprocessor directives, header files, and GCC build stages.
• Module 2: Pointers, Arrays & Memory Management: Pointer arithmetic, multi-dimensional arrays, stack vs heap, `malloc`, `calloc`, `realloc`, and `free`.
• Module 3: Custom Structures & Data Structures: `struct`, `union`, bitwise operations, linked lists, binary trees, and function pointers.
• Module 4: File I/O & Low-Level Debugging: Standard file operations (`fopen`/`fread`), command-line args, Valgrind memory audits, and GDB debugging.

Target Audience & Prerequisites

Designed for computer science students, embedded systems developers, backend engineers, and programmers seeking deep hardware insights. Basic logic and math skills required.
