🛠️ Usage

Requirements

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

Instructions

1. Compiling the library

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

For all mandatory functions:

$ make

For bonus functions:

$ make bonus

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

To clean all files generated while doing a make, go to the path and run:

$ make fclean

3. Using it in your code

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

#include "libft.h"
