Create a class, called StudentRecord, which represents one row of data for our student. A StudentRecord should contain the following fields: 1. . Student ID Midterm * Assignments Final exam Final Mark . Letter Grade The final mark will be calculated as a weighted average of the assignments (20%), midterm (30%), and final exam (50%). The letter grade will be determined from the following table: Minimum 80 70 60 50 0 Maximum 100 79 69 59 49 Letter Grade 2.
