I've got a 2 dimentional array, defined as such: float **a; and allocated at run time. I'm just wondering the best way to write this to a file (using C++ I/O) and read it back in. Just to save reading raw data and putting it back into the array every time I start the program. [edited by - ShalRath on January 8, 2004 10:02:26 PM]

I''d say...

In binary, have two unsigned ints for the array dimensions, then the array row by row.

I don''t know what it would be for, but the less file usage the better, so maybe a read at the start, a write at the end, and nothing else in between.

blah blah blah.
