[Boost-users] erase and iterators

is this common practise for using an interator with erase? what i wish to do is interate through each item and delete the item if some condition is true. when i delete, i need to move back a step so that i dont miss an item. for (std::vector<int>::iterator it = vect.begin(); it != vect.end(); it++) { if ((*it) == 5) { // some condition vect.erase(it); it--; // step back } } or would it be best to use a reverse iterater? (or possible?) for (std::vector<int>::reverse_iterator it2 = vect.rbegin(); it2 != vect.rend(); it2++) { if ((*it) == 5) { // i'm not actually sure how to erase with a reverse iterator??? vect.erase(it2); } }
