Can you remove elements from a std::list while iterating through it?

Question

I\'ve got code that looks like this:

for (std::list::iterator i=items.begin();i!=items.end();i++)
{
    bool isActive = (*i)->update();
    /         


        

Answer 1

You want to do:

i= items.erase(i);

That will correctly update the iterator to point to the location after the iterator you removed.
