Hi

I have a class X and I'm using a list to store X instances. Later in
the project I realized that I needed to search that list for certain
instances and I thought of storing the found objects in a vector<X *>.

My problem is - how can I run through list<X>, with a
list<X>::iterator, and use a pointer to point to the selected objects?

I'm thinking of rewriting all instances of list<X> and use list<X *>
in order to be compatible with the search function.

class X
{};
std::list<X> myList;
std::list<X>::iterator find = myList.begin();
X* pointer = &(*find); // * -> get a reference to
the objct. & get the addrss.
std::vector<X*> data;
data.push_back(pointer);

Thanks, it worked!
