Inserting & deleting data in files

[globos]

Hi all, here is the problem :

I use the standards classes provided by fstream.h to do some stuffs on files. These stuffs are :
-inserting(at the beginning) data to a file
-deleting the inserted data

For the moment I have to re-create the file when I do the preceding operations i.e. to insert data I create a new file then I copy the data and the rest of the whole file.
This method is quite expansive, are there other issues?
It might be physically impossible.

ofstream xx("datafile"//creates a new file or destroy
//the containt of the old file
xx<<&quot;hello&quot;;//write to it
cc.close();//save file

Thank you for your quite response, but it does not solve my problem, what you gave me erase the file. I want to insert data(not destroy) anywhere in the file without having to do an entire copy of it.

Later, I would like to be able to delete the added data, the final goal is to do a little ofuscator on files. --
