C++: Interface as Concept

The document discusses C++ memory handling and object-oriented programming concepts like stack and heap memory allocation, dynamic memory allocation, copy constructors, and class interfaces. It provides examples of stack allocation versus dynamic/heap allocation. It also demonstrates how to properly implement copy constructors to avoid shallow copy issues when composing objects. Finally, it presents an example of defining a class interface (abstract base class) for reusable and extensible code, allowing different object types like cars and airplanes to both be controlled by a remote control class.
