/* c only version
int holds around 65,536 values (it is at a minimum 16 bit)
short is actually half of an integer, in that it will be at a max 16 bit
long is a 32 bit integer
char is only 8 bits
unsigned char is the clearest way to manipulated a byte


% is modulo - 2 ? for binary?   & is AND operator | is OR operator 
<< is left shift  */
