C Programming--linked lists and importing?

Question

How do I import a file into a linked list?

Answer 1

A linked list is a programming construct.
So you have to write the part of the program that reads the file. Then you decide what part of the file data goes into the linked list. You also decide on what type of linked list you are creating.
Now you have that part of the program written you write the next part that does something with the linked list.

So basically it is all down to you.
