Hybrid or Multipath Inheritance in C++

As we know that inheritance is the process of extending the source code of one class to another class

Definition: It’s interesting to know that we can have the combination of both multilevel and Hierarchical Inheritance
This type of inheritance is also known as Multipath or Virtual Inheritance

Syntax to Implement Multipath Inheritance

The class that is acquiring the behaviors is called child class or derived class or subclass
The class from which behaviors are taken is called parent class or superclass or base class

class parent
{
----;
};
class child1: access parent
{
-----;
//contains properties of both
//parent+child1
};
class child2: access parent
{
----;
//contains properties of both
//parent+child2
};
class child2_1: access child2
{
-----;
//contains properties of both
//parent+child2+child2_1
};
class child1_1:access child1
{
-----;
//contains properties of both
//parent+child2+child1_1
};

Here you can see that there is a hierarchal inheritance from parent to child1 and child2

multilevel inheritance from parent to child1 to child1_1(path1) and parent to child2 to child1_2(path2).

Example Program demonstrating MultiPath Inheritance in C++

class A
{

public:
void m1()
{
cout<<"\n m1 from class A";
}

};

class B: public A//B class inherits A as Parent
{

public:
void m2()
{
cout<<"\n m2 from class B";
}
//contains data of A+B

};

class C: public A//C class inherits A as Parent
{

public:
void m3()
{
cout<<"\n m3 from class C";
}
//Contains data of A+C

};

class D:public B//multilevel inheritance from A->B->D 
{

public:
void m4()
{
cout<<"\n m4 from class D";
}
//contains data of class A+B+D

};

class E:public C//multilevel inheritance from A->C->E
{

public:
void m5()
{
cout<<"\n m5 from class E";
}
//contains data of class A+C+E

};

main()
{

D d;//contains A+B+D properties 
d.m1();
d.m2();
d.m4();
E e;//contains A+C+E properties 
e.m1();
e.m3();
e.m5();

}

O/P:

m1 from class A
m2 from class B
m4 from class D
m1 from class A
m3 from class C
m5 from class E

Hiarrichal Inheritance from A-B and A-C

Class B contains 2 methods m1() from class A and m2() by its own
Class C contains 2 methods m1() from class A and m3() by its own

Multilevel inheritance from class A-B-D and A-C-E

Class D contains 3 methods m1() from class A and m2() from class B and its own method m4()
Class E contains 3 methods m1() from class A and m3() from class C and its own method m5()
