ft_printf - Recreating the printf Function

Introduction

This project involves creating a custom printf function, named ft_printf, that mimics the behavior of the original printf function from the C standard library. The goal is to implement a subset of format specifiers and conversions to handle character, string, pointer, decimal, integer, unsigned decimal, and hexadecimal printing.

Project Files

• Makefile: Contains rules for compilation (all), cleaning (clean), force cleaning (fclean), and recompilation (re).

• libftprintf.h: Header file containing function prototypes and necessary declarations.

• *.c: Source files containing the implementation of the ft_printf function and related helper functions.

How to Use

1. Clone the repository:

   git clone https://github.com/your-username/ft_printf.git

2. Navigate to the project folder:

   cd ft_printf

3. Compile the library:

   make

   This will generate the libftprintf.a library.

4. Use the library in your C projects:

   • Copy the libftprintf.a file to your project folder.

   • Include the libftprintf.h header file in your C files.

   • Compile your project with the library:

     gcc -Wall -Wextra -Werror -o your_program your_file.c libftprintf.a

5. Clean up:

   make clean

   This removes object files.

6. If you want to remove the library and object files:

   make fclean

Functionality

The ft_printf function can be used to format and print data to the standard output. It supports the following conversions:

• %c: Prints a single character.
• %s: Prints a string.
• %p: Prints a void pointer in hexadecimal format.
• %d / %i: Prints a decimal (base 10) number.
• %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.

Additional Notes

• The ft_printf function does not implement the buffer management of the original printf.
