c++: vector::erase called with an iterator

Question

I am working on a vector of structs.

When I am trying to call this function with iterator, like this:

vec2.erase (vec2.begin()+iter2);

it sends me this error:

"no match for 'operator+' in '(+vec2)->std::vector<_Tp, _Alloc>::begin [with _Tp = wordstype, _Alloc = std::allocator<wordstype>]() + iter2'" 

Can I send an iterator (or any other parameter)? If yes, what is the problem?

Answer 1

You cannot add iterator to iterator.

iter2 already points to the concrete place in a vector, so you can write:

iter2 = vec2.erase(iter2);

instead.
