    David decided to use a different code in his answer to Sam. This time, he was putting A instead of B,
B instead of C, and so on. His message to Sam shown on the right was very short. Can you understand?
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

    Sam guessed David's code, and he replied: ZESDQ, RBGNNK. When David's little sister saw the message,
she felt puzzled. She couldn't read it at all. But David was very happy that his sister couldn't read his message!
     Lots of people use codes to send secret messages. In a war, secrets are very important so soldiers often
send each other messages in code. Nowadays, we can use computers to make and break difficult codes. Even
before computers, people invented other machines to do this. 
    Here's a famous machine that Germans used in the Second World War (1941-1945). It's called the Enigma
Machine. The machines were very big, heavy and expensive. Every day they changed the codes automatically,
and this made it almost impossible for anyone to break the codes. The person sending a message had one
machine, and the person receiving the message had another.
