Removing and Inserting Elements
- How do you remove an element from a vector?
- If the order is not important, overwrite
the element to be removed with the last element of the
vector, then shrink the size of the vector.
void erase(vector<string>& v, int pos){ int last_pos - v.size() - 1; v[pos] = v[last_pos]; v.pop_back(); }
