How to deallocate an element in a vector of pointers?

Question

So I have a vector of pointers like so:

vector<Example*> ve;

I fill this vector with pointers like this

Example* e = new Example();
ve.push_back(e)

But when I want to remove them, how do I assure they get deallocated? Is this enough?

ve.erase(ve.begin() + 1)
delete ve[1]

Answer 1

You have to do it the other way round, of course:

delete ve[1];
ve.erase(ve.begin() + 1);

However, it's vastly more preferable to use smart pointers (such as std::unique_ptr) instead of raw pointers when expressing ownership.
