Question

Forgive me as my C++ is very rusty. But I am in a bind. I am trying to make a custom list that have methods to return the front most, and back most items.

ElementType& front() throw(string*)
{
   if (empty())
      throw new string("Empty Vector");
   else
      return(first)
}

My main problem is that I don’t have the actual first item, I have a pointer to it and I have no idea how to go about taking a reference of what the pointer is pointing it, using only the pointer. I’ve tried things similar to:

ElementType& *first

or

&*first

but I can’t get them to play nicely. Any advice would be greatly appreciated.

Answer 1

If first is a pointer to your element, *first will give you a reference to it.
