Usage
All the files are compiled on Ubuntu 14.04 LTS
Compile your code with gcc -Wall -Werror -Wextra -pedantic -std=gnu89 *.c -o _printf
Include the "main.h" header file on the functions using the _printf()
Create a file (main.c) with the contents below
Example
#include "main.h"
/**
* main - Entry point
*
* Return: Always 0
*/
int main(void)
{
_printf("Hello, World!\n");
_printf("This is a %% sign\n");
_printf("%c and %s and %c\n", 'A', "test", 'B');
