libft is a project designed to reimplement the functions of the C Standard Library (libc) and create your own custom standard library. In this project, you can improve your programming skills by rebuilding your basic functions in the C language on your own. In addition, you are also expected to implement some data structures such as linked lists and the functions related to these structures.
This project helps you to better understand the C language by creating on your own the basic functions needed when programming in C. It also gives you the opportunity to practice understanding data structures and building your own libraries.
