Descending sort by name 5. Exit 5. If user choose menu '1', then the student data in ascending sort based on score. 6. If user choose menu '2', then the student data in descending sort based on score. 7. If user choose menu '3', then the student data in ascending sort based on name. 8. If user choose menu '4', then the student data in descending sort based on name. f user choose menu '5', then the program will ends Please run the EXE file to see the sample program.
