Question
Create a Student Grading Application using an Object Oriented Language of your choice. Which Adds, Edits, and Deletes student assignments onto a storage medium, with grades per student – per assignment – separated per C lass . Assignments must be displayed in 2 groups - Homework and Test. Grades for each assignment per student must be calculated along with an overall Class grade for each student ( displayed in both percentage and Letter grade).
a. Program must include
i. Subprograms with parameter passing
ii. Abstract Data types
iii. Encapsulation
iv. Exception / Error Handling
v. Must ve rify only valid scores are entered per assignment
vi. Documented for maintenance purposes
Also, Create a script that installs your entire application (including any Data files needed) . The install script must create a folder on the computers C - drive and copy any application files to this folder . For Windows OS , install an Icon (that executes the Application) on the Desktop (this icon must appear on the Desktop of a ny user that logs into the computer ) .
