Multiple Inheritance in C++

Inheritance is one of the core feature of an object-oriented programming language. It allows software developers to derive a new class from the existing class. The derived class inherits the features of the base class (existing class). In this tutorial we will study and understand the concept of Multiple Inheritance in C++.

Multiple Inheritance in C++

In C++ programming, a class can be derived from more than one parents. When a class is derived from two or more base classes, such inheritance is called Multiple Inheritance. Multiple Inheritance in C++ allow us to combine the features of several existing classes into a single class.

Ambiguity in Multiple Inheritance

In multiple inheritance, a single class is derived from two or more parent classes. So, there may be a possibility that two or more parents have same named member function. If the object of child class needs to access one of the same named member function then it results in ambiguity. The compiler is confused as method of which class to call on executing the call statement. Here’s an example of such program:

This problem can be solved using scope resolution(::) function to specify which function to class either base1 or base2
