This repository tracks my journey through the 42 Common Core curriculum.
It includes complete project implementations, evaluation processes, comprehensive documentation, and full solutions for all completed projects.
Status: ✅ Completed
Complete implementation of the foundational C library containing essential functions for memory handling, string manipulation, character checks, and linked list operations. This library serves as the foundation for all future 42 projects.
Key Features:
- Standard C library function reimplementations
- Memory manipulation functions
- String and character utilities
- Linked list operations (bonus part)
Status: ✅ Completed
Implementation of a function that reads a line from a file descriptor, managing static variables and buffer handling efficiently.
Key Features:
- Buffer-based reading with configurable
BUFFER_SIZE - Static variable management for multi-call persistence
- Handles multiple file descriptors
- Memory-efficient line extraction
Additional Resources:
- Get-Next-Line Evaluation Process — Evaluation scripts, tests, and validation tools
🔹 Printf
Status: ✅ Completed
Custom implementation of the C standard library printf function, supporting multiple format specifiers and variadic functions.
Supported Conversions: %c %s %p %d %i %u %x %X %%
Key Features:
- Variadic function implementation
- Clean dispatcher design
- Direct output via
write(2)(no buffering) - Norm-compliant code structure
Additional Resources:
- Printf Evaluation Process — Testing suite and evaluation materials
Status: ✅ Completed
Advanced sorting algorithm project that sorts integers using two stacks and a limited instruction set, with multiple optimization strategies.
Key Features:
- Four sorting strategies: Simple O(n²), Medium O(n√n), Complex O(n log n), and Adaptive
- Benchmark mode for performance analysis
- Disorder metric calculation
- Comprehensive error handling
- Custom doubly-linked stack implementation
Performance Targets:
- 100 numbers: < 700 operations (excellent)
- 500 numbers: < 5500 operations (excellent)
Status: ✅ Completed (18/18 exercises)
