It initializes
two variables, franIsTired and franMustWakeUpEarly, to true and false, respectively. Then, in the third line of code
(not including comments!), we determine that Fran will go to sleep if and
only if the "and" operation is true -- that is, if both inputs
to the "and" operation are true. In this case, the first input is
true and the second input is false. Since "and" requires both
inputs to be true in order for the output to be true, but one of the inputs
is false, the output will be false. So, the variable bedTime will store the value false.
Also, take note
that the variable names used here are lengthy. How you decide to program is
up to you, but often times it's better to have lengthier variable names that
are readable, rather than short, obfuscated variable names like "i"
or "zz". (The names in this example may have gone overboard,
though.)
