Instructions to use

Clone this repository in you local computer using a terminal:

• $> git clone https://github.com/gapima/Libft.git [libft_path]

After cloning the lib in your local reposiory you run some commands you can find in Makefile:

• $> make all: or just make compiles only the mandatory parts
• $> make bonus: compiles the bonus part
• $> make clean: deletes the object files created during compilation
• $> make fclean: executes the clean command and also deletes the libft.a
• $> make re: executes the fclean command followed by the all command
• $> make rebonus: executes the fclean command followed by the bonus command

To use libft in your projects you need to include its header:

• #include "libft.h"

To compile your projects that use libft you need to use the flags:

• $> ... -lft -L [path/to/libft.a] -I [path/to/libft.h]
