The Libft project is a fundamental part of 42, aimed at providing a strong foundation in C programming.
This custom library includes a variety of essential C language functions designed to promote learning and practice of key concepts.
Implementation of basic functions: The library contains custom implementations of standard C functions, such as string manipulation, memory management, mathematical operations, and linked list manipulation.
Libft's functions serve as a foundation for future projects within the 42 curriculum. They provide a solid set of tools to tackle more advanced and complex tasks in subsequent projects.
In addition to basic functions, this Libft version includes the implementation of ft_printf for output formatting and get_next_line for efficient reading of lines from files or standard input. These functions have been integrated to enable their direct use from the Libft library.

Clone the repository:
Open your terminal and run the following command to clone the repository:
git clone git@github.com:Ismaelm42/Libft.gitGo into your local repository folder. The project uses a Makefile to manage the build.
makeThe make command will compile the project and generate the libft.a library.
Additional commands:
make reDeletes and recompiles the project from scratch.
make cleanRemoves object (.o) files generated during compilation.
make fcleanRemoves object files and the library (.a).
After compiling the library, you can use it in your projects. Make sure that your source code file includes the corresponding header (libft.h). You can include it in your source code file as follows:
#include "libft.h"When compiling your program, be sure to link it to the libft.a library:
gcc my_program.c libft.a -o my_program
