vector of struct of vector, clear() issue

[CFLam]

Hello all,
If I define the following class:

class MyClass{
  struct myItem {
     int myInt;
     vector<string> myStr;
 }
 vector<myItem> MyVector;
}

When I call MyVector.clear(), it will handle everything for me or I need to do it myself as follow:

 for (auto& A:WorkingClass.MyVector)
    A.clear();
 WorkingClass.MyVector.clear();

Thanks.

MyVector.clear() is enough.

Calling clear on a MyClass::MyVector will call destructors on all of its elements (which call dtors on their elements...) so the contained strings and vectors will delete themselves.

@Peter87 & @tpb, thanks for the clarification.
