ft_printf

ft_printf is a 42 Madrid Common Core project in which you have to recode the libc library printf function.

About the project

ft_printf is a variadic function that will allow you to format any input and send it through the terminal standard output stdout. It means that this function must take a dynamic number of variables and get their values.

Mandatory parts

• Function protoype: int ft_printf(char const *, ...);
• It's not necessary to implement the original printf buffer management.
• Your function will be compared to the original printf.
• To create your library you must use the ar command. libtool is forbidden.
• Your libftprintf.a file must be created in the root folder of the project.

Conversions

• %c for characters.
• %s for strings.
• %p for void * pointers.
• %d for base 10 decimal numbers.
• %i for base 10 integers numbers.
• %u for base 10 unsigned decimal numbers.
• %x for base 16 lowercase hexadecimal numbers.
• %X for base 16 uppercase hexadecimal numbers.
• %% for the % character.

Compilation

Requirements

• C compiler: gcc, cc, etc...
• make utility.
• libft library in the project root folder.

Make commands

• make: compile project.
• make clean: deletes compilation files except the executables.
• make fclean: deletes all compilation files.
• make re: executes make fclean and make.

Build project

1. Clone the repository:

   git clone https://github.com/RaulSoftDev/ft_printf.git

2. Build the project:

   make

3. Use the library in your project:

   #include "ft_printf/libftprintf.h"

4. Compile your project:

   gcc -Wall -Wextra -Werror *.c ft_printf/libftprintf.a
