Hi all,
I'm programming a speech coder for analysis, but the problem is I have to write the code to work on a frame by frame basis,so for each frame, i dump the parameters into a file,which is grand.Now the problem after the first frame is gone and it comes to the second frame,it writes over the file made earlier,any suggestions to solve this??I have one method,I dump everything in a static array for the 50 frames and then dump these into the file but this isnt very efficient.Any help will be greatly appreciated.

Overwriting data in a file is usually that you've opened it using the wrong parameters. Stick ios::app into the file open function, to get it to append data to the end, or ios::ate to leave the file pointer At The End.

The way you're dumping your data sounds as efficient as possible to me, but I'm not well up on program efficiency yet.
