Libft - Library of functions in C

Description

Libft is an individual project in 42 that makes us recreate standard C library functions for future projects and have a deeper understanding about basic data structures and algorithms.

Instructions

1. Compiling the archives

To compile the proiect, go to its path and run:

For mandatory functions:

$ make

2. Cleaning all binary (.o) and executable files (.a)

To delete all files generated with make, go to the path and run:

$ make fclean

3. Using it in your code

To use this project in your code, simply include this header:

#include "libft.h"
