How do I get the address of a specific node in an STL container list?

Question

I'm trying to grab the address of a specific node in an STL list. I have set up an iterator that successfully goes through each node, but I want to capture a specific nodes address so that I can edit it. I've created temporary variables that hold that nodes property, but it never actually applies these changes since its not a pointer, it just replicates the node and now there is two identical nodes.

                sf::VertexArray* temp;
                for (std::list<sf::VertexArray>::iterator it = vertexManager.begin(); it != vertexManager.end(); it++)
                {

                    temp = it;
                }

I get that this is going to capture each node and override the previous one, but I can't figure out the syntax to do this.

The code above gives the error

Note: if `temp` is only used in the `for` loop, consider moving its definition into the loop and making it a reference rather than a pointer. Eg `sf::VertexArray & temp = *it;` A bit simpler and safer than the pointer version. — user4581301, Apr 14 '20 at 04:25
