In the game, the computer flips a virtual coin 50 times, and the object is
|
| 7 | 9 |
for you to guess whether the coin will come up heads or tails each time.
|
|
| 21 | 23 |
randomness thrown in, too.

This version of the game is written in Erlang, based largely on the version
|
| 24 | |
written in BASIC by Steve North appearing in *More BASIC Computer Games*,

|
| 26 | 28 |
heads and tails are called `Y` and `N`.

Running
|
| 29 | 31 |
-------
|
| 30 | 32 |
|
| 31 | |
Start an Erlang shell, load the `flip` module, and run `flip:start()`.
|
|
33 |
To build the `flip` module, run the script `make.sh` from the root
|
|
34 |
directory of the distribution.
|
|
35 |
|
|
36 |
After the module has been built, the game can be played by running the
|
|
37 |
script `flip` in the `bin` directory. This script can be run from anywhere;
|
|
38 |
it knows to locate the module in the distribution directory.

Playing the Game
|
|
41 |
----------------
|
|
42 |
|
|
43 |
Each time the computer prompts you with a question mark, type 'Y' to
|
|
44 |
guess that the flip was heads, or 'N' to guess that the flip was tails.
|
|
45 |
A correct guess will be signalled by an asterisk printed before the
|
|
46 |
next question mark. At the end of the run (by default 50 flips,) your
|
|
47 |
score will be printed.
