C printf

This project is a C implementation of the printf function. It supports a subset of the standard C printf functionality, including:

• Formatting of integers, floating-point numbers, and strings
• Handling of various conversion specifiers (e.g., %d, %f, %s)
• Support for custom conversion specifiers

The project adheres to the Betty coding style and uses a combination of macros and functions to achieve its functionality.

Requirements

• Allowed editors: vi, vim, emacs
• All files will be compiled using gcc version 20.04 LTS with the options -Wall -Werror -Wextra -pedantic -std=gnu89
• All files should end with a newline character
• A README.md file is required and should be placed in the root directory of the project
• Your code should use the Betty style and will be checked using betty-style.pl and betty-doc.pl
• Global variables are not allowed
• No more than 5 functions per file
• You are not allowed to use the main function in any of your files that are not the main source file
• The prototypes of all your functions should be included in your header file named main.h
• Don't forget to push your header file
• All your header files should be include-guarded

Authorized Functions and Macros
