🗣️ About

The aim of this project is to code a C library regrouping usual functions that you'll be allowed to use in all your other projects.

For detailed information, refer to the subject of this project.

🚀 TLDR: this project consists of coding basic C functions (see below), which are then compiled
into a library for use in other projects of the cursus.

Usage

Requirements

The library is written in C language and thus needs the gcc compiler and some standard C libraries to run.

Instructions

1. Compiling the library

To compile the library, run:

$ cd path/to/libft && make

2. Using it in your code

To use the library functions in your code, simply include its header:

#include "libft.h"

and, when compiling your code, add the required flags:

-lft -L path/to/libft.a -I path/to/libft.h
