As you
can
see,
each
number
printed falls
between
2
and
12.
We
are able to
put both of our
generators
and the adder
on
the
same
line
since the dice are always
both thrown
at
the same
time,
and only the total
is
of interest here.
Why
would
the following
be wrong?

Answer:
Adding random numbers
created
by two
generators,
each picking numbers between
1
and 6
will
create
many
more sums which
equal
3, 4, 5, 6, 7, 8,
9,
10
and 11 than a
single
generator
which picks an equal
amount
of
numbers
1
through 11
(to
which
we
add
1,
to
make
the range 2 through
12).
Rules of the
Game
In
its
simplest
form, the
game
goes like this:
1,
The
player
rolls
the
two
dice.
If
he
rolls
a
sum
of 2
(called
"snake eyes"), a 3
(called
"cock-eyes") or a
12
(called
"boxcars")
on
the
first roll,
he
loses
and
the
game
is
over.
That's "craps".
2, If
the player
rolls
7 or
11
on
the
first
throw,
(called
"a natural"),
he wins and
the
game
is
over.
3, If
any other
number
is
rolled,
it
becomes
the player's "point".
He
must keep
rolling
until
he
either
"makes
his
point" by
getting the
same
number
again to win, or
rolls
a
7,
and
loses.
EXERCISE
19-1
:
You
already
know
far
more
than enough
to
complete
this
program.
Do
it.
Put
in all
the
tests,
print
lines,
etc. to
meet
the rules
of the
game and
tell
the player
what
is
going on.
It
will take
you
awhile to
finish,
but
give
it
your
best
before
you
turn over to
Part
C
(User's
Programs) under Craps
for a
sample
solution.
Good
luck!
