git clone https://github.com/kukinpower/ft_printf.git

cd ft_printf

git submodule update --init to clone libft

make to compile library

Makefile works with rules: re clean fclean main main clean

Rule main compiles with main and runs a.out

Compiles with flags: -Wall -Wextra -Werror

ft_printf() uses libft library functions. And compiles with it.

my libft project

#include "libftprintf.h"

Then use as standard printf() with a format string.
