Read&Writee in file

i want to copy the contents of one file to another file.But using the following code only first line is copied;

Code:

---

QFile f("/root/Desktop/n.txt");
    f.open(QIODevice::ReadOnly | QIODevice::Text);
     QFile f1("nn.txt");
 f1.open(QIODevice::WriteOnly | QIODevice::Text);
 
     QTextStream in(&f);
   QTextStream out(&f1);
 
   while(!f.atEnd())
   {
  in>>q;
  out<<q;
 
}
   f.close();
   f1.close();

Why don't you use QFile::copy?

how is 'q' defined?

q is of type QString.i want to copy line by line,so that i can get some details seperated from the file.

1. Operator >> reads word not line.
2. Use QTextStream::readline.

@Leisok: thanks... i also wanted to know how to write the data line by line..

Did you try using operator << ?
