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.
