The libft project takes up the concept of the D06 of the swimming pool

Libft

The libft project takes up the concept of the D06 of the swimming pool, to make you write a library of useful functions that you can then use in the vast majority of your C projects this year and save you a lot of time.

This project ask you to write a lot of code that you have already done during the pool, which makes it a great time to take stock of your progress.
