My teacher ask to make a program that can: Insert record in front Insert rec

My teacher ask to make a program that can:

Insert record in front
Insert record at the end
Insert in between
Search node record
Delete record in front
Delete record at the end
Delete record in between

Using Data structure Linked List type. But I'm really
confused about the codes and I can't go through. Please help
Thanks in advance. Also here is my unfinished code if
someone can make changes it will be more good.
