Zenith Series

Inheritance, Polymorphism, and Virtual Functions in C++
After creating classes and objects, there is a need to build type hierarchies, reuse code through inheritance, and provide flexible behavior via polymorphism. These mechanisms enable extensible systems where new classes can be added without modifying existing code.
Zenith Course is a set of materials that helps systematically master inheritance, polymorphism, virtual functions, and related concepts. You will receive step-by-step explanations, code examples, practical tasks, and common usage patterns in real scenarios.

What's inside Zenith Series:

• Module 1: Inheritance — base and derived classes, access specifiers (public, protected, private inheritance), constructors and destructors in hierarchy, call order.
• Module 2: Method overriding — overriding base class methods in derived class, using override keyword, calling base methods via Base::method().
• Module 3: Virtual functions and polymorphism — declaring virtual, dynamic binding (late binding), polymorphism via pointers and references, example with different shape types.
• Module 4: Pure virtual functions and abstract classes — pure virtual (=0), abstract classes, defining interfaces, mandatory overriding in derived classes.
• Module 5: Multiple inheritance — inheriting from multiple base classes, diamond problem, virtual inheritance to resolve it.
• Module 6: Additional OOP aspects — final (preventing inheritance and overriding), friend functions and friend classes, access rules in complex hierarchies, common mistakes and how to avoid them.

Who this material is for:
Suitable if:

• You already create classes and objects, use constructors and operator overloading
• You want to build class hierarchies and use polymorphism
• You plan to write more flexible and extensible code

Not suitable if:

• You have not yet worked with classes, objects, and encapsulation
• You are looking for STL containers, templates, or multithreading right away

What you will be able to master after completing it:
Create class hierarchies through inheritance
Override methods and use virtual for polymorphic behavior
Write polymorphic code using pointers and references to base class
Create abstract classes and interfaces to define contracts
Use multiple inheritance and virtual inheritance when needed
Apply final, friend, and other modifiers for access control
Recognize and fix typical errors in inheritance hierarchies
Write code that is easy to extend with new types without changing base logic
