1) Don't put two pits in the same room.
2) Don't put bats and pits in the same room. (you will never hit the bat)
3) Don't start the player in a room with a pit or bad, if possible. Some
caves are so crowded the loop may go on forever, so we give up after 100
tries to put them in a safe location (as long as it's not with the wumpus).
4) Make the manpage reflect reality WRT the default number of rooms.
Bug #3 pointed out by salo.
games in a row. Also modify change made in rev 1.18 to work correctly.
take_action() returns 1 if the player dies, causing the game to allways
exit after any death, now the game correctly asks if the player would
like to play again.
The weights here are taken from
http://www.iupac.org/publications/pac/2003/7508/7508x1107.html
and have been rounded to four significant figures in all cases.
In the case of elements that have no isotopes stable enough for
reasonable measurement, numbers have been updated from Zumdahl,
"Chemistry", Fifth edition and are presented (as before) in parentheses.
2) Cesium is now C{a}esium
3) A number of new elements have been added at the end of the periodic
table.
Although the traditional spelling in commonwealth countries is
"Sulphur", the official IUPAC name of the element is "Sulfur", and
even the Royal Society of Chemistry now spells it "Sulfur".
- replaced direct POSIX read/write with stdio, which made the code simpler.
- added even more error checking.
- restructured the code to make each function fit on one screen
(well, except one).
- now the code reflects the intended purpose of the program.
- return 0 instead of EXIT_FAILURE on success.
