ft_printf

💡 About

This project consists of coding a library that contains a simplified version of the printf function.

My implementation of the printf function from the C standard library. This is a project done as part of the 42 school cursus.

🛠️ Usage

Requirements

The function is written in C language and needs the gcc compiler and some standard C libraries to run.

Instructions

1. Compiling the library

To compile the library, run:

$ git clone https://github.com/Wdaoudi/ft_printf
$ cd ft_printf
$ make

2. Using it in your code

To use the library functions in your code, simply include its header:

#include "ft_printf.h"

📋 Supported Conversions

The function supports the following conversions:

Conversion	Description
%c	Single character
%s	String
%p	Pointer address
%d	Decimal (base 10)
%i	Integer (base 10)
%u	Unsigned decimal
%x	Lowercase hexadecimal
%X	Uppercase hexadecimal
%%	Percentage sign

📊 Testing

You can test the function with:

gcc -Wall -Wextra -Werror main.c libftprintf.a && ./a.out

Example main function:

int main(void)
{
    ft_printf("Character: %c\n", 'A');
    ft_printf("String: %s\n", "Hello, world!");
    ft_printf("Pointer: %p\n", (void *)0x123456);
    ft_printf("Decimal: %d\n", 42);
    ft_printf("Integer: %i\n", -42);
    ft_printf("Unsigned: %u\n", 4294967295);
    ft_printf("Hexadecimal: %x\n", 255);
    ft_printf("HEXADECIMAL: %X\n", 255);
    ft_printf("Percentage: %%\n");
    return (0);
}
