Recoded printf() function from libc 🖨️

What is ft_printf ❓

The aim of this project is to recode printf function and be able to reuse it in future projects. It is primarily about learning what variadic functions are and how to work with them. The key to a successful ft_printf is well-structured and good extensible code.

🖥️ School instructions for the project:

• project must be written in accordance with the 42 Norm
• allocated memory space must be properly freed -> No leaks!
• we must submit a Makefile with the flags -Wall, -Wextra and -Werror
• submit project to assigned git repository
• prototype of ft_printf should be: int ft_printf(const char *, ...);
• It will manage the following conversions: cspdiuxX%
• You must use the command ar to create your librairy, using the command libtool is forbidden

📝 A small description of the required conversion:

• %c print a single character
• %s print a string of characters
• %p The void * pointer argument is printed in hexadecimal
• %d print a decimal (base 10) number
• %i print an integer in base 10
• %u print an unsigned decimal (base 10) number
• %x print a number in hexadecimal (base 16), with lowercase
• %X print a number in hexadecimal (base 16), with uppercase
• %% print a percent sign

🛠️ How to use it?

Compilation:

To compile run $ make

To clean '.o' files run $ make clean

To use it in code include header:

#include "ft_printf.h"
