✨ What is Printf?

The printf function is one of the most versatile and well-known functions in the C language. From a testing aid to tabulation method, printf is a very powerful and important tool in every dev's kit. This project aims to recreate the behaviour of the original MacOS's printf, including its basic error management, some of its flags, minimum field width stipulation and most of its basic conversions.

📑 List of Conversions

Specifiers
Format Specifier	Description
%	% followed by another % character writes % to the screen.
c	writes a single character.
s	writes a character string.
p	writes an implementation-defined character sequence defining a pointer address.
d or i	writes a signed integer to decimal representation.
u	writes an unsigned integer to decimal representation.
x or X	writes an unsigned integer to hexadecimal representation.

💻 Technologies

This Project was made with:

• C
• Makefile
• Shell
• gcc

👷 How to Run

Requirements

The function is written in C language and thus needs the gcc compiler and some standard C libraries to run.

Instructions

1. Compiling the library

To compile, go to the library path and run:

$ make

2. Using it in your code

To use the library functions in your code, simply include its header:

#include "ft_printf.h"
