Polymorphism and Structure

Lessons

1. 01 Inheritance The measurement of whether the base subobject a derived object carries inside it stands at the same address, and is part of a single construction/destruction sequence. 1 min read
2. 02 Virtual Functions and Vtables The measurement of whether a virtual call through a base pointer or reference always works with the same object, independent of the expression's static type. 1 min read
3. 03 Abstract Classes and Interfaces The measurement of how a pure virtual function guarantees that no instance can be constructed from the base class, and that an interface is a pure contract carrying no data. 2 min read
4. 04 Multiple Inheritance and the Diamond Problem The measurement of how the second base subobject in multiple inheritance does not share the same address as the derived object, and how a common ancestor in diamond-shaped inheritance doubles without virtual inheritance. 1 min read
5. 05 Exceptions The measurement of how many times a thrown object is copied while being caught, which parts a construction cut short by an exception destroy, and how a temporary object is copied fewer times than a named local. 1 min read
6. 06 Namespaces and Code Organization The measurement of how two symbols with the same name are separated by namespaces, and that a using declaration and a namespace alias are not a new symbol but an access path to an existing one. 2 min read
7. 07 Type Conversion Operators The measurement of whether static_cast, dynamic_cast, const_cast, and reinterpret_cast access a reference as a part of an existing object or as a copy in a new one, depending on the target type. 11 min read
