C Learning Projects

Author: Joshua Alana

Welcome to my C Learning Projects repository! This collection of projects and exercises is part of my extended journey to master C programming and system-level concepts, ultimately preparing me for Linux kernel development. Over the next 6-8 months, I will be working on various projects covering a wide range of topics in C, including memory management, system calls, process control, data structures, and kernel modules.

During this period, I will also be actively seeking internship opportunities in big tech companies to gain practical experience and apply my growing skills in real-world scenarios.

Project Breakdown

1. Data Structures

• Implementations of core data structures such as:
  • Linked Lists
  • Binary Trees
  • Hash Tables
  • Heaps
• These implementations focus on efficient memory use and pointer management in C.

2. System Programming

• Projects that explore:
  • Process management using fork, exec, wait
  • Inter-process communication (IPC) via pipes and message queues
  • A simple command-line shell that supports I/O redirection and process piping.

3. Memory Management

• Custom implementations of memory management functions:
  • malloc and free
  • Paging and virtual memory simulations
• Projects that simulate memory allocation for dynamic data structures and applications.

4. Kernel Projects

• Exploring the Linux kernel:
  • Writing and loading kernel modules (e.g., "Hello World" module)
  • Custom system calls
  • Kernel-level memory management and process control.
