Converting chars to binary - Version 2

This is another version of a char variable to binary program.

#include <stdio.h>
#include <string.h>

/*
 * When translating from char to binary we are using this map:
 *
 * Dec.	   Bin.			Hex.
 *   1 <=> 00000001 <=> 0x01 => 1*2^0
 *   2 <=> 00000010 <=> 0x02 => 1*2^1
 *   4 <=> 00000100 <=> 0x04 => 1*2^2
 *   8 <=> 00001000 <=> 0x08 => 1*2^3
 *  16 <=> 00010000 <=> 0x10 => 1*2^4
 *  32 <=> 00100000 <=> 0x20 => 1*2^5
 *  64 <=> 01000000 <=> 0x40 => 1*2^6
 * 128 <=> 10000000 <=> 0x80 => 1*2^7
 */

/*
 * This function returns the correct order as well.
