"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can write an integer to a file by opening an output file stream, and then writing the integer to it. Something like:

#include <fstream>

ofstream fout;

int i=233;
fout.open("data");
fout<<i;
fout.close();

Reading it back in is the analogous process with an file input stream.

You can write an object to file by saying,

out.write( (char*)&myobject, sizeof(myobject) );

where out is an instance of ofstream.

Cheers!

Did any of those responses help?

If any did, you should select the response(s) that helped you, and grade it (them).

If not, perhaps a clarifying question would help.
