Installation

You can git clone the repository using https protocol

git clone https://github.com/Nihilantropy/ft_printf.git

access the directory and run the make command

cd ft_printf && make

Now you have your ft_printf library 📖! To use it you only have to add the ft_printf.h (inside the include folder) into your program header! Once you've done that, you can compile your fresh new program with the -L/path/to/libftprintf.a (change accordingly) and the -lftprintf flag 🇮🇹! Now that you know how to use it... let's make it!

ft_printf 🛠️

Welcome to the world of ft_printf! 🎉 This project is all about recoding the legendary printf function from the C library. If you’ve ever wondered how printf works under the hood or wanted to take your C skills to the next level, this is your chance!

📜 Project Overview

The aim of this project is to create your very own version of printf(), a function that’s as versatile as it is essential in C programming. You'll dive into the world of variadic functions and discover how to format and print output in various ways.

🎯 Mandatory Part

What You Need to Do

• Function Prototype: int ft_printf(const char *format, ...);
• Handle These Conversions:
  • %c - Print a character.
  • %s - Print a string.
  • %p - Print a pointer in hexadecimal format.
  • %d - Print a decimal number.
  • %i - Print an integer.
  • %u - Print an unsigned decimal number.
  • %x - Print a number in lowercase hexadecimal.
  • %X - Print a number in uppercase hexadecimal.
  • %% - Print a percent sign.
• External Functions Allowed: malloc, free, write, va_start, va_arg, va_copy, va_end
• Library Creation: Use ar to make your library (libftprintf.a) and keep it in the root of your repo.

What to Keep in Mind

• Skip the buffer management of the original printf(). Focus on making your function work flawlessly with the given format specifiers.
• Make sure your implementation is robust and handles errors gracefully.

🎁 Bonus Part (not present in this project)

Feeling adventurous? Try out these bonus features to make your ft_printf even cooler (not present in this project):

• Flag Management: Implement flags like -, 0, ., and handle minimum field widths.
• Additional Flags: Add support for # and +.

Note: The bonus features will only be reviewed if your mandatory part is spot on—no pressure! 😉

🛠️ Common Instructions

• Language: C
• Norm Compliance: Follow the 42 Norm to the letter. This applies to both mandatory and bonus parts.
• Error Handling: No segfaults or memory leaks allowed! Ensure your code runs smoothly.
• Makefile Must-Haves:
  • Include rules for $(NAME), all, clean, fclean, and re.
  • Avoid unnecessary relinking in the bonus rule.
• Libft Integration: If you’re using libft, make sure to include it in a libft directory and compile it first.

🚀 Submission

Once you’re done, submit your work to your Git repository. Double-check that all files are correctly named and included. Your project will be graded based on what’s in the repo, so make sure everything is in tip-top shape!

Congratulations! With ft_printf added to your toolkit, you’re one step closer to mastering C programming. 🎉💻
