The average is 76.4666.

desidude, since your sum and count are modified after the while loop, only the last value of your numbers gets added to sum, and count gets incremented once, from zero to one. And 77 is your last value.

  if ( fin >> val )
  {
    sum += val;
    ++count;
    min = max = val;
 
    while ( fin >> val )
    {
      if ( val < min )
      {

      if ( val > max )
