Thread: need advice again

Linked lists are your friend. If you don't know how to make one, use the handy dandy search function here, or go to google and search there.

To save you the head ache, use a double linked list, it'll be a breeze.

Create a linked list where each node contains a single line. When you are done, you go through your list, or as you're creating, whatever, go back three places, and print that node's data.

Here's the structure to get you started:

Code:

struct node {
    struct node *prev, *next;
    char * data;
};

Read a single line of text from your file, get it's length, malloc that size plus one for the 'data' field, copy it there, continue on your merry way. Hint: fgets() is your friend.

Quzah.
