Write a program to read test scores, process scores, and display a final report or save the report into a text file. A report isgenerated for a class of 4 students.A test score is an integer from 0 to 100. There are no extra credits.

It is called magic its value or presence is inexplicable without some additional knowledge. The term magic number also refers to programming practice of using numbers directly in source code without explanation. In most cases this makes as harder to read, understand, and maintain, although most guides make an exception for the numbers zero and r example, a program is more readable if menu items are defined as constants as shown in the right column. ractice: using "magic numbers” use the following format. Good practice: more readable using constants Use the following format. final int GRADE REPORT = 1; final int GRADE REPORT_IN FILE = final int EXIT = 3; 2; switch (choice) { case GRADE REPORT: h (choice) { se 1: // break; se 2: break; case GRADE REPORT IN FILE: break; se 3: // break; break; case EXIT: // break; } parallel arrays to store corresponding information of each student at the same index. t[] testone new int[4]; // Students' test one grades t[] testTwo new int[4]; // Students' test two grades uble[] average = new double [4]; // Students' average grades ar[] grade = new char[4]; // Students' letter grades Student one Student two Student three Student four 0 1 2 3 ndex value estone 0 1 3 ndex value estTwo 0 1 2 3 ndex value Jerage O 1 2 3 ndex value cade 8 to Grade Center! to generate and display a report. to generate a report and save it into a file. to quit. choice: When the program runs, this menu is displayed.
