Often the reason you want to reverse the vector is because you fill it by pushing all the items on at the end but were actually receiving them in reverse order. In that case you can reverse the container as you go by using a deque instead and pushing them directly on the front. (Or you could insert the items at the front with vector::insert() instead, but that would be slow when there are lots of items because it has to shuffle all the other items along for every insertion.) So as opposed to:
std::vector<int> foo;
int nextItem;
while (getNext(nextItem)) {
foo.push_back(nextItem);
}
std::reverse(foo.begin(), foo.end());
You can instead do:
std::deque<int> foo;
int nextItem;
while (getNext(nextItem)) {
foo.push_front(nextItem);
}
// No reverse needed - already in correct order
