I have a problem where the user enters in their grades from their homework and exams and then the program will tell the user what their grade is. I have everything worked out below but I am missing one key aspect. There are 12 homeworks and only the best 10 are used. How would I go about extracting the best 10 homeworks out of the 12 that are entered??

Will accept from keyboard your grades for this course
and generate the overall points out of 100 and the
equivalent letter grade based on the information
on the syllabus.
Homeworks (best 10 out of 12) 50%
Exams I & II 16%
Final Exam (comprehensive) 24%
Class Participation and attendance 10%
Grading Scale: (inclusive)
A+ 97-100
A 92-96
A- 90-91
B+ 88-89
B 82-87
B- 80-81
C+ 78-79
C 72-77
C- 70-71
D+ 68-69
D 60-67
E 0-59
