Recoded Printf function from Libc

Ft_Printf |  Cursus

Recoded Printf function from Libc. And learn about variadic functions.

What is the project about

This project has two parts organized in two level of difficulty: the mandatory and the bonus part. Mandatory only manages character, string, pointer, decimal, interger, unsigned decimal, hexadecimal and % sign. Bonus part requires to manage -0.# + flags. ft_printf project aims on learning the logic of having an unspecified number of arguments or variadic functions.

General Instrucctions

• The project must compile with a Makefile without relinking.
• Makefile has to contain at least this rules: $(NAME), all, clean, fclean and re
• The project must compile with -Wall -Wextra -Werror flags.
• After compiling a library named libftprintf.a file has to appear.

To compile the project

> make
> gcc main.c libftprintf.a
> ./a.out

Mandatory Instrucctions

Requirements

Prototype of the ft_printf function: int ft_printf(const char *, ...);

The Mandatory implements 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.

Here are the requirements: • 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
