  // Step 1. Open the input file and read in student records
  //         one by one, using recordTemp as the container. 
  //         After reading one record, call member function
  //         InsertRecord to insert the record into the array.
  //         So, you may use a loop like this:
  //
  //            for (i=0; i<numStudents; i++) {
  //              read a student record;
  //              InsertRecord(recordTemp);
  //            }

  // Step 2. Average student numerical grades and give the 
  //         letter grades. You can do this by calling 
  //         member function CalLetGrade.

  // Step 3. Print out student record in the order of letter
  //         grades. You can do this by calling PrintByGrades.

  // Step 4. Print out student record in the order of ranks.
  //         You can do this by calling PrintByRanks.
