Ccpp Inheritance in C Cpp
Inheritance lets a class reuse and extend another. A derived class (Dog) inherits the members of a base class (Animal) and can add its own. This models "is-a" relationships and avoids duplicating shared code. Syntax: `class Dog : public Animal { ... };`.
Polymorphism means "many forms": a base-class pointer or reference can point to any derived object, and calling a virtual function runs the version belonging to the actual object's type, decided at run time. Mark the base method `virtual` and override it in the derived class. This is how one loop can treat many different shapes/animals uniformly.
Always give a base class a virtual destructor if you delete derived objects through a base pointer, otherwise the derived part may not be cleaned up. Together, encapsulation + inheritance + polymorphism are the three pillars of OOP that C++ interviews test.
Ccpp Inheritance — Syntax
class Base { public: virtual void speak(); };
class Derived : public Base { public: void speak() override; };
