Libft

This repository contains my implementation of libft, a foundational C library developed as part of the 42 school curriculum.

🧩 About the Project

It reimplements essential standard C library functions and includes additional utility functions to use in future C projects. I added an edition that check pointers first to prevent any safety problems when used in other project.

• ✅ 100% written in C
• ✅ Norm-compliant
• ✅ Includes Makefile with all, clean, fclean, re, and bonus rules

📄 Based on the official libft subject

🔧 Build Instructions

To build the library:

make # builds libft.a using mandatory files

make bonus # includes *_bonus.c functions

make clean # removes object files

make fclean # removes object files and libft.a

make re # fclean + make

✅ Implemented Functions

Part 1 – Libc Reimplementation Functions like: ft_isalpha, ft_strlen, ft_memset, ft_strncmp, ft_atoi, ft_calloc, ft_strdup, ...

Part 2 – Additional Utilities Includes: ft_substr, ft_strjoin, ft_strtrim, ft_split, ft_itoa, ft_strmapi, ft_striteri, ...

Bonus – Linked List Tools Includes: ft_lstnew, ft_lstadd_back, ft_lstsize, ft_lstlast, ft_lstdelone, ft_lstclear, ft_lstiter, ft_lstmap
