# ft_printf 🖨️

This project is a custom implementation of the C library function `printf`, built from scratch. It replicates much of the functionality of the original `printf` function while offering a deeper understanding of variadic functions and formatted output.

## About the Project

The **ft_printf** project, part of the [42 School](https://42.fr/) curriculum, focuses on reimplementing the `printf` function in C. The goal is to replicate its core features, handle various data types, and gain experience working with variadic functions, which allow for functions to accept a variable number of arguments.

## Features

**ft_printf** replicates the main functionality of `printf`, with support for:

- Character and string printing

- Integer and unsigned integer printing (including hexadecimal)

- Pointer address printing

- Percentage sign printing

This project was completed without using standard library functions like `printf`, `sprintf`, or `snprintf`, ensuring a fully custom approach.

## Installation

To compile and integrate **ft_printf** into your project, follow these steps:

1. Clone the repository:

   ```bash

   git clone https://github.com/asut00/ft_printf.git

   cd ft_printf

   ```

2. Compile the library:

   ```bash

   make

   ```

3. You’ll get a `libftprintf.a` file that you can link with any C project:

   ```bash

   gcc yourfile.c -L. -lftprintf -o yourprogram

   ```

## Usage

To use **ft_printf** in your project, include the `ft_printf.h` header:

```c

#include "ft_printf.h"

```

You can now call `ft_printf` as you would with the standard `printf` function. For example:

```c

#include "ft_printf.h"

int main() {

    ft_printf("Hello, %s! Your score is %d.\n", "user", 42);

    return 0;

}

```

## Supported Conversions

The **ft_printf** project supports the following conversion specifiers:

| Specifier | Description                |

|-----------|----------------------------|

| `%c`      | Print a single character   |

| `%s`      | Print a string of characters |

| `%p`      | Print a pointer address    |

| `%d`/`%i` | Print an integer           |

| `%u`      | Print an unsigned integer  |

| `%x`/`%X` | Print a hexadecimal (lower/upper case) |

| `%%`      | Print a percentage sign    |
