What is Multiple inheritance in C++ OOP?

In multiple inheritance, the child class is derived from more than one parent class.

Ambiguity in Multiple Inheritance in C++ is the most common problem.

Difference between multiple and single Inheritance in C++

Here, i am showing you a comparison of multiple and single inheritance in C++.

MULTIPLE INHERITANCESINGLE INHERITANCE
In Multiple inheritance derived class have more than one base class.In Single inheritance derived class have only single base class.
More overhead in Multiple inheritance and  requires more run time as compared to single inheritance.Less overhead in single inheritance and  requires small run time as compared to multiple inheritance.
Multiple inheritance is a lot of close to generalization.Single inheritance is a lot of close to specialization.
Syntax of multiple inheritance is

Class DerivedClass_name : access_specifier Base_Class1, access_specifier Base_Class2, ….{}; .

Syntax of single inheritance is

Class DerivedClass_name : access_specifier Base_Class{};.

Multiple inheritance is more complex as compared to the single inheritance.Single inheritance is simple as compared to the multiple inheritance.
Multiple inheritance is supported by C++ but Multiple inheritance can’t be implemented in most of other programming languages e.g, C# and Java doesn’t support multiple inheritance through classes.Mostly all of the programming languages supports Single inheritance.

Difference between multiple and multi level Inheritance in C++

Here, i am showing you a comparison of multiple and multi level inheritance in C++.

Multiple InheritanceMultilevel Inheritance
In Multiple Inheritance a class inherits from more than one parent classes.In Multilevel Inheritance parent shares inherits with child and then child becomes parent of other class and share the resources of parent to its child.

Class Levels

Multiple Inheritance has two class levels namely, base class and derived class.Multilevel Inheritance has three class levels namely, base class, intermediate class and derived class.

 Usage

Multiple Inheritance is complex as compared to multi level inheritance and not widely used.Multilevel Inheritance is widely used as compared to multiple inheritance.
