Thanks for all the responses. The character array rand did not have a
null terminating character '\0', so the printf family of functions did
not know where to stop when using %s. I handled it a bit differently
and used someone's suggestion to print the hex value of each character
instead of trying to treat it like a null terminated string. The
reason I am printing the hex encoded value of each byte is because
some of the bytes translate to non-printable characters.
Thanks,
Axton
