ft_printf

ft_printf is a custom reimplementation of the standard printf() function from the C standard library. The purpose of this project is to deepen the understanding of variadic functions, which allow handling a variable number of arguments—a core feature in C programming. This project mimics the behavior of printf() by supporting a variety of format specifiers and ensuring efficient memory management.

Features

Supported Format Specifiers:

• %c: Prints a single character.
• %s: Prints a string.
• %p: Prints a pointer in hexadecimal format.
• %d: Prints a decimal (base 10) number.
• %i: Prints an integer (base 10).
• %u: Prints an unsigned decimal (base 10) number.
• %x: Prints a number in lowercase hexadecimal format.
• %X: Prints a number in uppercase hexadecimal format.
• %%: Prints a percent sign.

Installation

1. Clone the repository:

   git clone https://github.com/luis-ffe/ft_printf.git

2. Navigate to the project directory:

   cd ft_printf

3. Compile the library:

   make

Usage

To use ft_printf in your project, simply include it after compiling the library:

#include "ft_printf.h"

Then, call ft_printf as you would with the standard printf:

ft_printf("Hello %s, your score is %d!\n", "world", 100);

Requirements

• The project is written in C.
• Adheres to strict memory management (no leaks).

External Functions Used

• malloc, free, write
• Variadic functions: va_start, va_arg, va_copy, va_end
