This piece of code uses classes and the concept of object-oriented programming, hehe, but it doesn't use linked lists from data structures.
It's a large program that includes these four smaller programs:
1. Add function:
2. Delete function:
3. Display function:
4. Search function:
And so on... you'll have to figure it out yourself. This year, if we do a course project, it will probably involve graphical user interfaces. Uh~ so pitiful.
