Re: [Dev-C++] Sorting Linked Lists and Array Members

Simple (bubble)sort can look like this:

void swap(Node_ptr &list, Node_ptr n, Node_ptr next, Node_ptr prev) {
     n->ptr_to_next_node = next->ptr_to_next_node;
     next->ptr_to_next_node = n;
     if (prev) {
         prev->ptr_to_next_node = next;
     }
     else {
         /* we're at first node */
         list = next;
     }
}

void sort(Node_ptr &list) {
     bool swapped;
     do {
         swapped = false;
         for (Node_ptr n = list, prev = NULL; n && n->ptr_to_next_node; 
prev = n, n = n->ptr_to_next_node) {
             Node_ptr next = n->ptr_to_next_node;
             if (strcmp(n->word, next->word) > 0) {
                 swap(list, n, next, prev);
                 swapped = true;
             }
         }
     } while (swapped);
}
