how change this program to (Convert the ArrayFunctionExample with two dimentional array to keep the student ID and scores together as one array.)???

Say studentID[50] is 512 then score[50] will be the score for student 512.

If you have more than 1 score per student score[50][10], score[50][2], ... etc
