ft_printf

The ft_printf project challenges us to create a function that mimics the behaviour of the C standard library's printf() function, which prints formatted output to the standard output stream or a user-defined output stream.

Getting Started

To use the ft_printf function, simply clone the repository to your local machine. The library comes with a Makefile that includes the following rules:

• all: compiles the library
• re: recompiles the library
• fclean: removes all object files and the library
• clean: removes all object files

To compile the library, run:

make all

This will generate a .a file that you can link to your C projects.

Using the Function

To use the ft_printf function, include the ft_printf.h header file in your C source files.

#include "ft_printf.h"

int main(void)
{
    ft_printf("Hello, %s!\n", "world");
    return (0);
}

Supported Conversion Specifiers

It supports the following conversion specifiers:

Specifier	Output
%c	Character
%s	String
%p	Pointer address
%d	Signed decimal integer
%i	Signed decimal integer
%u	Unsigned decimal integer
%x	Unsigned hexadecimal (lowercase)
%X	Unsigned hexadecimal (uppercase)

Relation with libft Project

The ft_printf function is included in the libft project, which is a library of useful functions that are used in later projects at 42. You can find the libft project here.

Conclusions

The ft_printf function is a powerful tool for printing formatted output to the standard output stream or a user-defined output stream. This project has been added to the libft, which is a library of useful functions used in later projects at 42.
