Erasing elements from a vector

I want to delete some elements as I go and so dont want miss the iteration

I travers right now as follows

vector<double> distances;
for(size_t i=0; i<distances.size();i++)
{

}

How do I traverse from end to beginning so I can safely delete elements and yet access the element I want?

Answer 1

for (size_t i = distances.size() - 1; i >=0; --i)

However, you should use an std::remove_if instead
