multilevel inheritance in c++ private method

In C++, multilevel inheritance allows a derived class to inherit properties and behaviors from multiple base classes. When a base class has a private method, it is not directly accessible by the derived class. However, it can still be invoked indirectly through public or protected methods of the base class.

Here are the steps involved in multilevel inheritance with a private method:

1. Define the base class: Start by defining a base class that contains a private method. This private method can only be accessed within the base class and cannot be directly invoked by the derived class.

2. Define the first derived class: Create a derived class that inherits from the base class. The derived class can access the public and protected members of the base class but not the private method directly.

3. Define the second derived class: Now, create another derived class that inherits from the first derived class. This class can access the public and protected members of both the base class and the first derived class.

4. Access the private method: To access the private method of the base class, you can define a public or protected method in each derived class that invokes the private method of the base class. This way, the derived class can indirectly invoke the private method.

By following these steps, you can achieve multilevel inheritance in C++ even if the base class has a private method.
