![Algorithm ThreeDimensionalarrayApplication;
//This algoritm defines a 3 dimensional array called "Student" and keeps the points of 5 students.
Each student takes 4 courses and 3 points from each course. Here are the indexs will be used: "CNum"
keeps the course number; "stNum" keeps the student number; "Points" keeps the points of student that
takes from each exam of each course. "ExNum" is the count of exam of each course//
