In single inheritance, the derived class. Inheritance is a method that can derive or build new classes from the existing class. Here our main topic of discussion is the difference between single inheritance and multiple inheritance, two types of inheritance. In single inheritance, we only have one base class, which is inherited by a single derived class.
In multiple inheritance we have more than two base classes that are inherited in combination by a single derived class. Inheritance is characterized as single or multiple depending on the number of classes from which a class can inherit. Single inheritance is simple but restrictive. Multiple inheritance, on the other hand, is complex, but it allows a more natural definition of relations between classes.
A derived class can access the members of the base classes based on the access specifier by which the base class is inherited. The reason this isn't possible with class inheritance is because when you use class inheritance, you buy all existing class taxonomy. The derived class can access the members of the base class according to the access specifier specified during inheritance of the base class. Multiple inheritance allows the derived class to inherit combined features from more than one base class, i.
As in single inheritance, the derived class object will retrieve only the member function defined within the derived class. A better option would be to create a new base class from which both the amplifiers and the channel inherit, but even that has limitations. Actually, there are several different types of inheritance, and most of them are great for composing compound objects from multi-component objects.
