📣 ft_printf

💥 ft_printf is a recreation of the standard printf function in C.
No more guessing what’s printed—this project ensures precise and flexible formatted output. 🚀

📖 About the Project

ft_printf mimics the behavior of the printf function from the C standard library (<stdio.h>).
It supports formatted output with various conversion specifiers and flags.

Features:

• Handles the following conversion specifiers:
  • %c : Single character
  • %s : String
  • %d or %i : Signed integer
  • %u : Unsigned integer
  • %x or %X : Hexadecimal numbers (lowercase or uppercase)
  • %p : Pointer address
  • %% : Percent symbol
• Supports flags, width, and precision for formatting.

🚀 How to Use

Clone the Repository:

1. Clone the repository to your local machine:

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

2. Run the Makefile to compile the library:

   make
   This will create a libftprintf.a file that you can link to your projects.

3. To use the library in your project, compile your program with the following command:

   gcc -Wall -Werror -Wextra main.c -L. -lftprintf -o ft_printf_example

📚 Testing the Function

Example 1: Basic Test

ft_printf("Welcome to %s!\n", "ft_printf");
Output:
Welcome to ft_printf!

Example 2: Test with Integers

ft_printf("The number is: %d\n", 42);
Output:
The number is: 42

Example 3: Test Hexadecimal and Pointers

int num = 255;
ft_printf("Memory address: %p, Hex value: %x\n", &num, num);
Output:
Memory address: 0x7ffee36a7a4, Hex value: ff

🛠️ Supported Format Specifiers

  | Specifier | Description                          |
  |-----------|--------------------------------------|
  | `%c`      | Prints a single character            |
  | `%s`      | Prints a string                      |
  | `%d/%i`   | Prints a signed integer              |
  | `%u`      | Prints an unsigned integer           |
  | `%x/%X`   | Prints a number in hexadecimal       |
  | `%p`      | Prints a pointer address             |
  | `%%`      | Prints a percent symbol              |

🌟 Showcase

Here’s what ft_printf looks like in action:
ft_printf("🚀 ft_printf can handle %s, %d, and even %p!\n", "strings", 123, &main);
Output:
🚀 ft_printf can handle strings, 123, and even 0x7ffee36a7a4!
