problems with ifstream and ofstream!! help me please!!!

I have a nice save function, except for a minor (well major) problem. There are no errors at compile or anything like that. But when I run the program and it gets to a certain line of code I get a windows error that says "blah.exe has encountered an error and must be closed. Sorry for any inconvenience.......". You know the rest. I have windows xp. This happened once before when I didnt initialize a variable, i think. Anyhow, there is nothing like that that could cause a problem. I've zeroed in on the lines where the windows error pops up:

ofstream save("player.txt")

save>>current_room->id>>"\n";

save>>current_weapon->id>>"\n";

there are 3 others. this is in main:

Code:

struct ROOM
{
ROOM* north;
ROOM* south;
ROOM* east;
ROOM* west;
int id;
};

ROOM chamber;
ROOM hallway;
chamber.north=&hallway;
chamber.id=1;

ROOM* current_room;

current_room=&chamber.north;

...so current_room points to another variable of type room, which has an element that points to another variable of type room. this isnt the exact code, but its just about exact. i pass current_room to my saving function. when i do save>>current_room->id;, i get the windows error. It also happens with other variables that point to something. i've even tried saying something like:

int id=current_room->id;

and using 'id' instead of 'current_room->id'.that doesnt even work and it is a regular integer! i know that i can use current_room and things that it points to in functions because there are many others that do. this just makes no sense at all to me. when i get home i'll post the exact code, but i've pretty much explained it all. It makes no sense! help!

ofstream save("player.txt")

save>>current_room->id>>"\n";

save>>current_weapon->id>>"\n";

If save is an ofstream object and you are writting stuff to it, don't you need to use << and not >>.

struct ROOM
{
ROOM* north;
ROOM* south;
ROOM* east;
ROOM* west;
int id;
};

ROOM chamber;
ROOM hallway;
chamber.north=&hallway;
chamber.id=1;

ROOM* current_room;

current_room=&chamber.north;

chamber.north is a pointer as is current_room, so you probably just need to say current_room = chamber.north.

i pass current_room to my saving function. when i do save>>current_room->id;, i get the windows error. It also happens with other variables that point to something.

Again, maybe a case of using >> where you should be using <<.

i know that i have all the sytax right for the structs and things, i was just writing taht code off the top of my head. also the << and >> are correct. i'll post the actual code later when i get home.
