_printf - Simulation of the C Standard Library printf Function

This is a project that simulates the C library function function printf. Our simulation function _printf is a variadic function which formats arguments into a character string and sends the formatted output to stdout.

Getting Started

These instructions will help you get a copy of _printf up and running your machine for development and testing purposes.

Prerequisites

This project has been implemented and tested on Ubuntu 14.04.5 LTS. Testing was done using VirtualBox 5.2.0 (https://www.virtualbox.org/wiki/Downloads) via Vagrant 2.0.0 64-bit (https://www.vagrantup.com/downloads.html).

Installation

Follow the steps outlined below in order to get started with _printf:

1. Clone the repository into your directory of choice by running this command

$ git clone https://github.com/squidcarroll/printf.git

After cloning the repository, you should see the files below:

FILE	DESCRIPTION
holberton.h	Header file containing directives and function prototypes
_printf.c	Soure file containing program that simulates printf
_putchar.c	Source file containing a putchar simulation function
print_functions.c	Source file containing functions used for printing data
helper_funcs.c	Source file containing functions used for manipulating data

2. Implement the compilation process by running this command

$ gcc -Wall -Werror -Wextra -pedantic -I $PWD/printf printf/*.c <FILENAME>.c

Note: <FILENAME> is a placeholder that should be replaced with a file name of your choosing.

3. Try it out by using _printf in some of your code, e.g.

#include <holberton.h>

int main(void)
{
	_printf("I love %s strings!\n", "printing");
	return (0);
}

Will have the following output:

$ I love printing strings!

Notes

This version of _printf works with the following format specifiers:

%c - Displays a character

%s - Displays a string

%d or %i - Displays an integer in decimal form

%% - Prints a single % character
