Bale ganito yung algorithm
main:
1. Get the data from file and put on array
2. Let the user choice an option
2.1 add.
add student from array, delete the file then use array to create new file.
2.2 update
update student from array, delete the file then use array to create new file.
2.3 delete
delete student from array, delete the file then use array to create new file.
2.4 show
show the array
2.5 compute
compute the data in array
2.6 SortBest
sort the array then show
2.7 SortWorst
sort the array then show.
Bale may function ka na mag aacquire ng array at magcecreate ng file using that array para tawag nalang ng function at hindi paulit-ulit yung code.
