/* Further Adventures

 *

 * 1) Run the program

 *

 * 2) Play the game a few times.

 *    e.g. guess(2)

 *

 * There are three blocks of code covering the

 * three outcomes for a guess:

 * too low, too high or correct.

 *

 * 3) Update the second condition to

 *    (userNumber < secret)

 *

 * 4) Update the messages to match the

 *    new condition.

 *

 * 5) Swap the first and second conditions so

 *    the second condition uses the strict

 *    equality operator.

 *

 * 6) Update the messages to match the

 *    new condition.
