Welcome to the ft_printf!

ft_printf is the project, which recodes printf.

A format specifier follows this prototype :

%[flags][width][.precision][length]specifier

It works in the following conversions :

flags	length	specifier
-0# +	l ll h hh	diuoxXfegcspn%

The relationship chart between length and specifier

length	d i	u o x X	f e g	c	s	p	n
(none)	int	unsigned int	double	int	char *	void *	int *
hh	signed char	unsigned char					signed char *
h	short int	unsigned short int					short int *
l	long int	unsigned long int		wint_t	wchar_t *		long int *
ll	long long int	unsigned long int					long long int *

Mandatory part

• The prototype of ft_printf should be

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

• You have to recode the libc’s printf function
• It must not do the buffer management like the real printf
• It will manage the following conversions: cspdiuxX%
• It will manage any combination of the following flags: -0.* and minimum field width with all conversions
• It will be compared with the real printf
• You must use the command ar to create your librairy, using the command libtool is forbidden.

---

Bonus part

• If the Mandatory part is not perfect don’t even think about bonuses
• You don’t need to do all the bonuses
• Manage one or more of the following conversions: nfge + o
• Manage one or more of the following flags: l ll h hh
• Manage all the following flags: # + (yes, one of them is a space)
