This document discusses types of inheritance in object-oriented programming including single, multilevel, multiple, hierarchical, and hybrid inheritance. It provides code examples and explanations of: - Single, multilevel, multiple, hierarchical, and hybrid inheritance structures - Access specifiers for base and derived classes and their effects - Calling base class constructors from derived class constructors - The virtual keyword and dynamic binding in inheritance The document contains code examples demonstrating inheritance concepts like defining base and derived classes, accessing members of base classes, and calling base class constructors from derived classes. It also provides explanations of multilevel, multiple, and hybrid inheritance with diagrams.

FOR INSTANCE:

25. Multilevel Inheritance :-
Definition:
“It is the inheritance hierarchy wherein subclass acts as a
base class for other classes”
It is implemented by defining at least three classes.
In multilevel inheritance, there is one base class and the
remaining two is derived class.

26. Declaration :-
class A
{………..
……….}; // Base class
class B : public A
{………..
……….}; // B derived from A
class C : public B
{……….
………}; // C derived from B

28. Hybrid inheritance :-
Definition:
“Inheritance hierarchy that reflects any legal combination of
other four types of inheritance.”
Simple word:-
“The method of combining any two or more forms of
inheritance in single form is called hybrid inheritance.”

class D: public b, public c
{……….
……….};

32. Constructors in Inheritance :-
• Base class constructors are automatically called for you if
they have no argument.
• If you want to call a superclass constructor with an argument,
you must use the subclass's constructor initialization list.
• C++ supports multiple inheritance (for better or worse), so the
base class must be referred to by name, rather than "super()".

33. Constructor Example :-
class SuperClass
{
public:
SuperClass(int foo)
{ // do something with foo }
};
class SubClass : public SuperClass
{
public: SubClass(int foo, int bar) : SuperClass(foo)
{ // do something with bar }
};

34. Virtual keyword determines if a member function of a class can
be over-ridden in its derived classes.
The non-virtual member functions are resolved at compiling
time and it’s called static binding. However, the c++ virtual
member functions are resolved during runtime and it’s called
as dynamic binding
