About

This project is about implementing the printf() built-in function.

The following converions are handled in this project:

• %s string
• %u unsigned decimal
• %i integer
• %d decimal
• %p pointer
• %x lower case hexadecimal
• %X upper case hexadecimal
• %c character
• %% percentage

NOTE: Main file is uploaded to check, test and compare the project conversions outpust to the main printf built-in command

Development

Makefile creates a Files directory which hold the project content

The content include:

1. inc : ft_printf.h
2. src : ft_printf.c ft_character.c ft_string.c ft_putnbr.c ft_hexa.c ft_ pointer.c ft_unsigned.c main.c
3. obj : ft_printf.o ft_character.o ft_string.o ft_putnbr.o ft_hexa.o ft_ pointer.o ft_unsigned.o main.o

NOTE: The best way to test your code is by simply comparing your function output with printf() outputs as it show below:

Challenges

In This project the main challenge i faced is to learn and to know how to work with the variadic functions. Sense the built-in command printf take infinte number of arguments it was a challenge to figure how to implement the same function in my code, and the variadic functions were the answere. Implementing va_start(), va_arg() and va_end() gave my function the ability to accept infinite number of arguments.
