README

        
This repository contains my implementation of the ft_printf function, 

a fundamental part of the 42 School curriculum.

The goal is to recreate the standard C printf function with specified 

features and constraints while deepening understanding of variadic functions, 

memory management, and formatted output.

About ft_printf

  printf is a variadic function, meaning it accepts a variable number of arguments. 

  The first argument is a format string that defines how the subsequent arguments are formatted and displayed.

Key Concepts

  Variadic Functions

  The  library provides macros for working with variadic functions:

    va_start: Initializes a va_list for use.

    va_arg: Retrieves the next argument in the list.

    va_end: Cleans up the va_list when done.

  Return Type

  Returns the total length of characters printed.

  If an error occurs, ft_printf returns -1.
