A lil help with linked list

[Night_Prawler]

Hi i'm currently trying to figure out how to load characters from a text file into a linked list. Anyone out there can help me with this ? a guide? i'm stuck!

thanks first for all the help

Oh forgot to mention, i need it in C, not C++ .

Look at dynamical memory allocation malloc() or alloca() ie:

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

typedef struct my_array {
      char letter;
      struct my_array* next;
      struct my_array* prev;
} my_array;


int main()
{
  FILE* file;
  my_array* cur;
  my_array* next;
  /* allocate room for atleast one array member */
  cur = (my_array*) alloca(sizeof(my_array));
  cur->prev = NULL;
  cur->next = NULL;
  file = fopen("my_file", "r");
  while(!feof(file))
  {
    if(EOF != cur->letter = fgetc(file))
    {
      /* since we could read something 
       * we need to allocate room for one more letter 
       */
      next = (my_array*) alloca( sizeof(my_array));
      /* alter cur to point at active member in array */
      cur->next = next;
      next->prev = cur;
      next->next = NULL;
      cur = cur->next;
      cur->letter = '\0';
    }
  }
  fclose(file);
  while (cur != NULL)
  { /* NOTE printing in reverse order */
     printf("%c\n", cur->letter);
     cur = cur->prev;
     free (cur->next);
  }
  return 0;
}

It's a very simple run through a dynamicaly allocated array, I use alloca() instead of malloc(), since it is more safe when dealing with memory allocation, only drawback is, it dosn't work on every system.
The program hasn't been tested, and theres virtualy no error checking, but it should give you an idear.
