  dear rooters:

  i feel there is something wrong with the 'fin >>' method.

  my code is like this:
  // tmp.cpp
  void tmp(){
  ofstream fout ("tmp.dat");
  Double_t arr;

  for(int i=0;i<3;++i){
   fout << i*0.1;
  }
  fout.close();
  ifstream fin("tmp.cpp");
  for(i=0;i<3;++i){
   fin >> arr;
   cout << i << ' ' << arr << endl;
  }
  }

  it should be 0 0.1 0.2
  but the output turns out to be 0.1 0.2 0.2
  it seems that it take 00.1 as 0.1

  i am not sure if i have made any mistake. what is ur opinion?
  thank u.

  zhou, dong
