ft_printf

Because ft_putnbr() and ft_putstr() aren’t enough

Summary:

The goal of this project is to recode printf(). This exercise provides an opportunity to improve programming skills, especially in dealing with a variable number of arguments. Upon successful completion, you can integrate your ft_printf() into your libft for use in other school C projects.

I. Introduction

Discover the popular and versatile C function, printf(). This exercise enhances programming skills and introduces variadic functions in C. A successful ft_printf requires well-structured and extensible code. After completion, integrate ft_printf() into your libft for future use.

II. Common Instructions

• Project must be written in C.
• Follow the Norm for coding standards.
• Functions should not quit unexpectedly, and memory must be properly managed.
• Submit a Makefile for compilation.
• Include basic Makefile rules: $(NAME), all, clean, fclean, and re.
• To turn in bonuses, include a bonus rule in your Makefile.
• If using libft, copy its sources and associated Makefile into a libft folder.
• Encouraged to create test programs for self-testing and peer evaluation.

III. Mandatory Part

• Program name: libftprintf.a
• Turn in files: Makefile, *.h, /.h, *.c, /.c
• Makefile rules: NAME, all, clean, fclean, re
• External functs.: malloc, free, write, va_start, va_arg, va_copy, va_end
• Libft authorized: Yes
• Description: Write a library containing ft_printf(), a function mimicking the original printf(). Recode the printf() function from libc.

Requirements:

• Don’t implement the buffer management of the original printf().
• Handle the following conversions: cspdiuxX%
• Use ar command to create the library. Using libtool command is forbidden.
• libftprintf.a must be created at the root of your repository.

Conversions to Implement:

• %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.

IV. Bonus Part

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)

Note: The bonus part will only be assessed if the mandatory part is PERFECT.

V. Submission and Peer-Evaluation

Turn in your assignment in your Git repository. Only the work inside your repository will be evaluated during the defense. Double-check file names for correctness.
