quick question about fstream

[fotoni2]

I have open a file for reading and writing.

fstream file;
file.open ("file.dat", ios::in | ios::out);

I need read and replace some information et the beginning of file and then jump to the end of file for writing.

Can I go to the end of file for writing without closing this stream and then opening in different mode?

Thanks!

ios_base::end may help, as may seekg(). You may find out more about these in the following link.
