Following is a difference file from the old Battleship game (the one
with curses) to a newer one with some bug fixes and several additions.
The three #defines near the top of the resulting file change the way
the game plays:
NOBLITZ If defined: Players always alternate
If undefined: Turns continue as long as player hits
NOASK If defined: Computer sees whether it hits or misses
If undefined: Computer asks if it hits or misses
SEEMISS If defined: Computer misses show up on players screen
If undefined: Computer keeps track of its own misses
Also, I changed the strategy slightly so that it's less deterministic. And
the program checks LOGNAME for the player's name, or uses Stranger if LOGNAME
is undefined.
The difference file follows. If you call it battle.dif, and the original
source battle.c, then the shell command
(cat battle.dif; echo '1,$p') | ed - battle.c >battle.new
will create the new version, battle.new.
