libft

📌 Description

Libft is a custom implementation of standard C library functions developed as part of the 42 Yerevan curriculum. The project focuses on understanding how low-level functions work and building a personal reusable C library.

---

⚙️ Features

• Reimplementation of core libc functions (strlen, memcpy, atoi, etc.)
• Advanced string and memory manipulation
• Dynamic memory allocation (malloc, calloc, free)
• Full linked list implementation
• Clean and modular code structure

---

🛠️ Technologies

• C
• Linux
• Makefile

---

🚀 Compilation

make

This will generate the libft.a static library.

---

🚀 Usage

Include the library in your project:

#include "libft.h"

---

📌 Example

#include "libft.h"
#include <stdio.h>

int main(void)
{
    char *str = "42 Yerevan";
    printf("Length: %d\n", ft_strlen(str));

    char *dup = ft_strdup(str);
    printf("Duplicate: %s\n", dup);

    free(dup);
    return 0;
}

🧠 What I Learned

• Memory management and pointer manipulation
• Implementation of low-level standard functions
• Writing clean, reusable, and modular C code
• Debugging and handling edge cases
• Understanding data structures (linked lists)

---

📂 Project Structure

• Libc functions – basic standard functions reimplemented
• Additional functions – extended string and utility functions
• Linked list – full implementation of list operations

---

🎯 Purpose

This project serves as a foundation for future C projects, allowing reuse of custom-built functions and deeper understanding of system-level programming.
