The Grade class should also include the following public member methods:

· char getLetterGrade() to return the letterGrade

· int getNumericGrade() to return the numericGrade

· string getStudent() to return the string student

· a constructor to prompt the user for a student name and a numeric grade, and to call calcLetterGrade()
