libft

---

This project gives the opportunity to recode functions that already exist in different libraries in c programming language and others that are not. the goal is to take in hand some functions that will help us in the next projects of the 42 cursus.

> How To Use The Library 📚

Compilation

To make a library without bonus part :

make

or

make all

To make a library with bonus part :

make bonus

Linking the library

To use libft in your code, you must add the include header to your code :

#include "$(path/of/the_libft)/Include\libft.h"

To Use The Library 📚 In Your Programe

gcc your "file .c" -lft -L path/to/libft.a -I path/to/libft.h

> Testing!

You can use these testers to test the functionality of functions :

> Goal!

After completing this project, I learned a lot of information about the basics of coding using C programming. Ultimately, the goal of this library is to be able to write clean code and know how to protect my functions and, of course, to familiarize myself with the library, which will help me a lot in future projects.
