Project introduction

This is my first project completed at 42 School, where the primary goal is to create a custom C library, libft, which consists of various standard and additional functions that will be invaluable throughout the curriculum.

Project Name

• Library Name: libft.a

Files to Submit

• Essential Files: Makefile, libft.h, ft_*.c
• Compilation: Compiled with flags -Wall -Werror -Wextra
• Library Creation: Utilize the ar command; the use of libtool is strictly forbidden.

Makefile Rules

• Available Commands: NAME, all, clean, fclean, re

Authorized Functions

• For this project, the usage of global variables is prohibited. Functions need to be concise and if necessary, split using the static keyword to limit their scope within files. All contributions must be located at the root of your repository, ensuring no unused files are included.

Using libft

• Incorporating libft in future projects allows for the reuse of well-structured and tested functions, streamlining the development process and enhancing code efficiency.

Description

The libft project involves writing a library that contains a set of functions mirroring those found in the C standard library, along with additional utility functions not included in libc. This project serves not only as an introduction to basic C programming but also as a foundational tool for the 42 curriculum.

Conversion Specifications

• Initially, recreate functions from the libc with similar behaviors and prototypes, prefixed with ft_. For instance, strlen becomes ft_strlen. Functions such as isalpha, isdigit, memset, among others, are to be redefined.

Requirements

• Technical Requirements:
  • No global variables.
  • Complex functions must be segmented and declared as static.
  • Place all files at the root of the repository.
  • Do not submit unused files.
  • Compile all .c files with -Wall -Werror -Wextra.
  • Create the library using the ar command.
  • libft.a must be situated at the root of the repository.

Implementation Overview

The project is divided into two parts:

• Part 1 - Libc Functions: Recreate specific libc functions.
• Part 2 - Additional Functions: Implement a series of additional functions that extend beyond the standard library, providing more tools for future projects.

Each function is carefully crafted to adhere to the specifications and behaviors of their original counterparts, with rigorous testing to ensure reliability and efficiency.
