17.2.3 Base and Member Destructors
Constructors and destructors interact correctly with class hierarchies (§3.2.4, Chapter 20). A constructor
builds a class object ‘‘from the bottom up’’:
[1] first, the constructor invokes its base class constructors,
[2] then, it invokes the member constructors, and
[3] finally, it executes its own body.
A destructor ‘‘tears down’’ an object in the reverse order:
[1] first, the destructor executes its own body,
[2] then, it invokes its member destructors, and
[3] finally, it inv okes its base class destructors.
