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()
