Libft

✅ Completed: Mandatory + Bonus
🏅 Score: 125/100

Libft is a custom implementation of some key functions from the C standard library, built as part of the curriculum at 42 School. The goal of this project is to deepen our understanding of low-level programming, memory management, and code optimization.

---

Features

• Standard C Functions: Replicates many standard library functions such as strlen, strcpy, strcat, and more.
• Memory Management: Includes functions like malloc, calloc, and custom implementations for memory manipulation (memset, memcpy, etc.).
• String Manipulation: Custom implementations for string operations (strdup, strchr, strncat, etc.).
• Additional Utilities: Includes useful utility functions not found in the standard library (e.g., ft_split, ft_itoa).

Getting Started

Prerequisites

• A Unix-like operating system (Linux, macOS, etc.).
• A C compiler (e.g., gcc).

Cloning the Repository

To clone the repository, run the following command:

git clone https://github.com/<your-username>/libft.git
cd libft

Functions Overview

Here is a quick list of the main functions implemented in this project:

Part 1: Libc Functions

• String Functions: ft_strlen, ft_strcpy, ft_strcmp, etc.
• Memory Functions: ft_memset, ft_bzero, ft_memcpy, etc.
• Character Functions: ft_isalpha, ft_isdigit, ft_toupper, etc.

Part 2: Additional Functions

• String Utilities: ft_substr, ft_strjoin, ft_split, etc.
• Number Conversions: ft_itoa, ft_atoi.

Bonus Functions

• Linked List Functions: ft_lstnew, ft_lstadd_front, ft_lstdelone, etc.

Installation

To build the library, simply run:

make

This will generate a libft.a file that can be linked to your projects.

Cleaning Up

To clean up compiled files, use:

make clean

To remove everything including the library file:

make fclean

---

Usage

To use the library in your project, include the libft.h header and link the library:

#include "libft.h"

int main(void) {
    char *str = ft_strdup("Hello, Libft!");
    ft_putstr_fd(str, 1);
    free(str);
    return 0;
}

Compile and link with:

gcc main.c -L. -lft -o my_program
