Re: [Boost-users] Remove elements from a list

I have a vector<float> source vector and a vector<int> keys.

I would like to remove all element in the keys from the source vector.

i.e. if the keys array is <1, 3, 4, 5> I would like to remove 1st, 3rd , 4th, 5th element from the source vector.

how can I do that?

Thank you.

I think this is as simple as possible: sort(keys.begin(), keys.end(), greater<int>()); // maybe use std::unique to remove duplicates BOOST_FOREACH(int key, keys) { assert(key >= 0); assert(key < data.size()); data.erase(boost::next(data.begin(), key)); }
