Question

In this code:

class myClass
{
    ...
    vector<myThing> thing(10);
    vector<myStuff> stuff(10);
    ...
}

vector<myClass> vecClass(10);
...
vecClass.clear();  /// calls destructor on myClass instances

Each element of vecClass holds 10 element vectors of thing and stuff. When clear() is called, does that make thing and stuff go out of scope, and thus be destroyed properly? Or is there something explicit that I have to do?

Answer 1

Yes, their destructors will be called. There is nothing else you need to do here.
