Compilation

To compile the library, run the following command:

make

This will generate the libft.a static library file.

To compile the bonus functions, run:

make bonus

Usage

Include the libft.h header file in your project and link against the libft.a library:

#include "libft.h"

// Your code here

Compile your project with the libft.a library:

cc -o my_program my_program.c -L. -lft
