Josh Katz's version of wc http://blog.gravypod.com/
#include <stdbool.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
// This is a "chunk" of characters that we can pull out and handle
// at one time. Since arrays in C are just collections of bytes we
// can iterate through a char array and pretend it was an int array.
// Using this union you can still get at the individual characters.
