    Makefile

    NAME, all, clean, fclean, re

  

  

	Arguments

	stack a: a list of integers

  

  

    External functions

    write(), malloc(), free(), va_start, va_arg, va_copy, va_end

  

  

	Libft authorized

	Yes

    

  

    Description

    Write a library that contains ft_printf(), a function that will mimic the original printf()

  

## Observations

You have to recode the `printf()` function from `libc`.

The prototype of ``ft_printf()`` is: 


``int ft_printf(const char *, ...);``

## Requirements

- Don’t implement the buffer management of the original ``printf()``.

- Your function has to handle the following conversions: ``cspdiuxX%``

- Your function will be compared against the original ``printf()``.

- You must use the command ``ar`` to create your library.

Using the ``libtool`` command is forbidden.

- Your ``libftprintf.a`` has to be created at the root of your repository

You have to implement the following conversions:

- ``%c`` Prints a single character.

- ``%s`` Prints a string (as defined by the common C convention).

- ``%p`` The void * pointer argument has to be printed in hexadecimal format.

- ``%d`` Prints a decimal (base 10) number.

- ``%i`` Prints an integer in base 10.

- ``%u`` Prints an unsigned decimal (base 10) number.

- ``%x`` Prints a number in hexadecimal (base 16) lowercase format.

- ``%X`` Prints a number in hexadecimal (base 16) uppercase format.

- ``%%`` Prints a percent sign.

# Bonus part

You don’t have to do all the bonuses.

## Bonus list:

- Manage any combination of the following flags: `-0.` and the field minimum width

under all conversions.

- Manage all the following flags: `# +` (Yes, one of them is a space)
