LIBFT

The first C project at 42. The goal is to create from scratch basic libC functions.

Features

• ft_printf : another projects that consists on implementing the libC printf function
• get_next_line : another projects that consists on implenting a readline function

Build

• build the library without ft_printf : make
• build the library with ft_printf : make ft_printf
