Multiple Inheritance

Multiple Inheritance is a feature of object-oriented concept where a class can inherit from more than one classes. In simple terms, if a child class having multiple parent then that is known as Multiple Inheritance. In c++ Multiple Inheritance is possible. Lets discuss this furthur with code examples.

Syntax
class Class3 : Class1, Class2 {
    //Fields and methods
}

CODE

EG 1 . Creating 2 classes called Rectangle and Car. Inheriting both to a new class called sampleClass

class Rectangle {
  public:
    double length, width;
    double Area() {
        return length * width;
    }
}

class Car {
  public:
    int totalNumberofPassangers;
    string color;
    void Drive() {
        cout << "Start Driving" << endl;
    }
}

//sampleClass can now access all the fields and methods of both Rectangle and Car.
class sampleClass : Rectangle, Car {

}

CODE EXPLANATION
In the above code, we created a class called sampleClass where we inherited 2 classes Rectangle and Car. Now sampleClass is having 2 parents. Here in C++ multiple inheritance is possible but when it comes to programming language like C# it is not possible. In the above code, just because sampleClass is inheriting Rectangle and Car it can access variables and methods present inside both the classes.
