Printf

Synopsis

This is a simple implementation of printf function that formats and prints data

Description

The _printf() function produces output according to a format which is described below. This function write its output to the stdout, the standard output stream. Returns the count of printed characters when the function is successful and -1 when the function fails.

The available convertion specifiers are:

• %c: Prints a single character.
• %s: Prints a string of characters.
• %d: Prints integers.
• %i: Prints integers.
• %b: Prints the binary representation of an unsigned decimal.
• %u: Prints unsigned integers
• %x: Prints the hexadecial representation of an unsigned decimal in lowercase letters
• %X:Prints the hexadecial representation of an unsigned decimal in uppercase letters
• %r: Prints a reversed string
• %R: Prints the Rot13 interpretation of a string

Usage

• All the files are to be compiled on Ubuntu 14.04 LTS
• Compile your code with gcc -Wall -Werror -Wextra -pedantic *.c
• Include the "holberton.h" header file on the functions using the _printf()

Example

#include "holberton.h"
#include <stdio.h>
/**
 * main - Entry point
 *
 * Return: Always 0
 */

int main(void)
{
	int a;
	int b;
	char *str;

	str = "school";
	a = _printf("%r\n", "Holberton"); /*expected: notrebloh*/
	printf("--->%d\n", a); /*expected: 10*/

	b = _printf("%r\n", str); /*expected: loohcs*/
	printf("%d\n", b); /*expected: 7*/

	b = _printf("%r\n", str); /*expected: loohcs*/
	printf("%d\n", b); /*expected: 7*/
	return (0);
}
