Linked List Problems

[Unregistered]

i have a problem with linked lists..here goes.

So far i have a struct like this;

struct details
{
char* firstname;
char* lastname;
int age;
};

struct node
{

struct details data;
struct node* link;

};

now how am i supposed to make a linked list from this. i know how to get user input but not how to populate a linked list.
could anyone please help?
thanx

You make a node point to the next one. But first u havta allocate memory for that new node.

mmmmm

struct node *newPtr;

newPtr = malloc( sizeof( struct node ) );

*currentPtr->nextPtr = newPtr;

only the theory

thanx

so now if i create an instance of the struct e.g

struct details d;

and have a user enter details for it e.g

d.firstname;
........
etc...

do i simply have to write sumthing like

ptrNew->next = d;

or smuthing different?

if u havent guessed i am new at this :-D

Thats exactly what i need to know as well, im (really) new to C progarmming and need all the info and help i can

Here's a simple linked list that counts from 0 to 9 with the root node being -1. It doesn't check for any errors, so keep that in mind:

#include <stdio.h>
#include <stdlib.h>

struct node
{
  int data;
  struct node *next;
};

int main ( void )
{
  int x;
  /* Declare all of the node pointers that we will
  ** need through the course of the program and
  ** allocate memory for the root node.
  */
  struct node *iter, *whisker, 
              *root = malloc ( sizeof *root );
  iter = root;
  iter->data = -1, iter->next = NULL;
  /* Populate the list by allocating memory for
  ** the current node's next pointer. This way
  ** we can then move iter to the next node easily.
  */
  for ( x = 0; x < 10; x++ ) {
    iter->next = malloc ( sizeof *iter );
    iter = iter->next;
    iter->data = x, iter->next = NULL;
  }
  /* Print the list with neato link symbols ^_^
  */
  for ( iter = root; iter != NULL; iter = iter->next )
    printf ( "%d %s", iter->data, ( iter->next != NULL ) ? "-> " : "\n" );
  /* Free the allocated memory so that the system
  ** can now use it. The list has been created, 
  ** used, and destroyed after this loop.
  */
  for ( iter = root; iter != NULL; iter = whisker ) {
    whisker = iter->next;
    free ( iter );
  }
  /* When we're through tidying up after outselves,
  ** we can end the program.
  */
  return 0;
}
