Removing an element from a vector
Author
I need to remove element #idx from vector v. How is this done? Like this? v.erase(&v.front()+idx);

Google says...
Anyway, from what I can see, really, unless your standard library is really weird, v.erase(&v.front()+idx) should work. Again, did you try it?
And, AFAIK, it is equivalent to &v.front() == v.begin() since vector iterators are pointers.

It should work but there appears to be some sort of detail that is missing...you may need to post some of the code.
You can use operator [] with the std::vector too
v.erase(&v[index]);
Although you should check that the index is a valid number
v.erase(&v[index]);
Although you should check that the index is a valid number
