Question #211836
definition of inheritance, types of inheritance with different access specifiers. All the concepts should be illustrated with appropriate diagrams and example programs.
Expert's answer
Inheritance in child class can be described as inheriting the features and behaviour/properties from the parent class. Here, the class that contains these members is called the base class and the class that inherits these members from the base class is called the derived class of that base class.
Access Modifiers
Following modifiers should be used at the time of creation of a derived class from a base class:
● Public
● Private
● Protected
The public data members can be accessed by any of its child class as well as the class objects.
Private data members are inaccessible outside the class.
Protected data members can only be accessed by the derived classes but are inaccessible using the class objects.
Inheritance: Syntax
Inherited class can be defined as follows:
class derived_class_name :access_modifierbase_class_name {
----
----
};
Inheritance: Types
There are six types of inheritance:
● Single Inheritance: Here, a child class is created from a single parent class.
● Multi-level Inheritance: Here, there is a series of derived classes, which means a derived class is created from another derived class.
● Multiple Inheritance: Here, a child class is created from more than one parent/base class.
● Multipath Inheritance: In this type of inheritance, a derived class is createdfrom other derived classes and the same base class of other derived classes.
● Hierarchical Inheritance: Here, more than one derived classes are createdfrom a single base class, and further, child classes act as parent classes formore than one child class.
