Come on--your book is worse than rubbish.
Agreed. That's why it has it's own bug reporting corner, and
also has a alert message.
It wasted my time,
Very sorry. Certainly my intention is/was not to waste your time.

a beginner... encrypting with XOR? give me a break.

IMHO you'd be much better off, and do your Indian compatriots a
great service, by removing what is laughably called "A to Z of C" from
the web. It's more like "A rotten reference to C". I applaud the
effort, but it's fourteenth-rate at best.
