[Dev-C++] adding nodes to the end of linked list

[chromatonus 7. <chr...@ho...>]

hi, my add_back function only adds one number to the list, it has to add 
nodes until i display the list (not included) , problem with the else 
section and probably more,

thanks!!

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

node add_back(node *&list, int info)
{
   node *skip = new node;
   node *tail = new node;
   if (list == NULL)
   {
      tail -> data = info;
      tail -> next = NULL;
      list = tail;
      skip = tail;
      delete tail;  // probably wrong...
   }
   else
   {
      tail -> data = info;
      tail -> next = NULL;
      skip -> next = tail;
      skip = tail;
      delete tail;
   }
}
