ft_printf

This repository hosts a re-implementation of the standard C library function printf, known as ft_printf. This project was developed as part of the programming training at School 42. The aim is to deepen knowledge of C programming by manually handling variadic functions and learning to precisely replicate standard library functionalities.

Project Overview

The ft_printf function mimics the behavior of the original printf, enabling formatted output by interpreting format specifiers embedded within strings. It handles a variety of format specifiers, including %s for strings, %d and %i for signed integers, %u for unsigned integers, %x and %X for hexadecimal numbers, %c for characters, %p for pointer addresses, and %% for a literal percent sign.

Features

• Mimics the standard printf function from the C Standard Library.
• Supports multiple format specifiers.
• Error handling similar to printf, including returning the number of characters printed or a negative number if an error occurs.

Requirements

• GCC compiler
• Standard C libraries

Setup and Compilation

1. Clone the repository:

   git clone https://github.com/madvil2/ft_printf.git

2. Navigate to the repository folder:

   cd ft_printf

3. Compile the library:

   make

   This will compile the library and create ft_printf.a.

Usage

To use ft_printf in your C projects, include the header file and link against the compiled library.

1. Include the header:

   #include "ft_printf.h"

2. Compile your project with ft_printf:

   gcc your_c_files.c -L. -lft_printf -o your_program_name

Testing

You can test the functionality of ft_printf using third-party testers, such as:

• Francinette

Run the tester according to its documentation to ensure that all aspects of ft_printf work correctly.
