    Is this C# or C++ If it's C# is there any particular reason you've chosen not to use a StreamReader

  • Darren Wang

    sorry guys, the problem is the infile has a hard return

  • gdanielg

    thank you for the tip, however it is still doing it.

    inFile.get(next);

    while (!inFile.eof())

    {

    outFile.put(next);

    inFile >>lastName >>firstName;

    inFile >>Q1>>Q2>>Q3>>Q4>>Q5>>Q6>>Q7>>Q8>>Q9>>Q10;

    average = ((Q1 + Q2 + Q3 + Q4 + Q5 + Q6 + Q7 + Q8 + Q9 + Q10)/10);

    outFile <<lastName<<" "<<firstName<<" "<<Q1<<" "<<Q2<<" "<<Q3<<" "<<Q4<<" "

    <<Q5<<" "<<Q6<<" "<<Q7<<" "<<Q8<<" "<<Q9<<" "<<Q10<<" "<< average <<endl;

    inFile.get(next);

    }

    inFile.close();

    outFile.close();

    any other suggestion would be helpful, it looks like it should work but....

    There is no way that this could be C#. It's C++.

    while (!inFile.eof())

    { inFile.get(next);

    outFile.put(next);

    eof is set when a read operation fails. You should call get before the loop, and again at the bottom of the loop, so that the eof is called after the operation that sets it, but before you write anything.
