The line I think you're questioning is ....
if ((ship_num=find_ship_by_id(GET_SHIP(c)))>=0&&ship_num<num_of_ships)
So in this case x = ship_num, y = find_ship_by_id, and z = 0
If he were to change it to what you said
if (x = y && x >=z ... )
then it would never allow a ship_num of 0 which he says above is
what he wants (>= 0) for if ship_num ends up being 0 then we'd
get
if ( 0 && 0 >= 0) which would fail.
Now doing it the way he did would be ...
if ( (0) >= 0) which would work.
Hope this makes sense.
Sorry I don't know an actual fix to the problem here.
Also, when you say you've never seen an if statement setup
like that before let me point you to some code you've
most likely looked at before.
comm.c
...
} else if ((port = atoi(argv[pos])) <= 1024) {
log("SYSERR: Illegal port number %d.", port);
exit(1);
}
...
Circlemud code is FULL of if statements like this.
