What is an “is a” relationship?
Inheritance:
Inheritance is the concept of acquiring the base class properties to the derived class. The term base class is referred to as general class and the derived class is the specialized class.
- It increases the functionality of the derived class.
- It also promotes the reusability of code (of the base class).
Explanation of Solution
“is a” relationship:
In object oriented programming, the “is-a” relationship is based on inheritance. When one object has a specialized version of another object, then there exists an “is-a” relationship between the two objects.
- When an “is-a” relationship occurs between two classes, which means that the derived class acquires all the properties of the base class.
- The derived class inherit the member function and member variables from the base class.
Example of “is-a” relationship:
- Parrot “is-a” bird.
- Circle “is-a” shape.
- Rose “is-a” flower.
