42-ft_printf

Introduction

The goal of this project is to recode printf( ). We will discover variadic functions in C.

Mandatory Part

Program name	libftprintf.a
Turn in files:	Makefile, *.h, */*.h, *.c, */*.c
Makefile:	NAME, all, clean, fclean, re
External functions:	malloc, free, write, 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( )

The prototype of ft_printf( ) is:
int ft_printf(const char *, ...);

Here are the requirements:

• Don’t implement the buffer management of the original printf( ).
• The function has to handle the following conversions: cspdiuxX%
• The function will be compared against the original printf( ).
• We must use the command ar to create the library.
• Using the libtool command is forbidden.
• The libftprintf.a has to be created at the root of the repository.

We 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.
