What is the primary purpose of using inheritance in programming?
What is the primary purpose of using inheritance in programming?
- To enable the creation of more specific classes that share common traits. (correct)
- To improve the performance of individual classes without any relation.
- To define characteristics common to a group of unrelated entities.
- To create a general class that has no specific function.
Which statement best describes a general class in the context of inheritance?
Which statement best describes a general class in the context of inheritance?
- It contains unique characteristics that do not relate to other classes.
- It serves as a template for defining common traits for related subclasses. (correct)
- It is a final class that cannot be inherited by any other classes.
- It can only contain methods but not attributes.
What is typically added by more specific classes that inherit from a general class?
What is typically added by more specific classes that inherit from a general class?

- Methods that override the inherited methods without retaining any features.

Study Notes
Inheritance in Programming
- Inheritance is a core principle in object-oriented programming (OOP).
- It allows for the creation of a general "parent" class that defines shared characteristics.
- The "parent" class is also known as a base class or superclass.
- Other, more specific "child" classes can inherit the characteristics of the parent class.
- These child classes are also known as derived classes or subclasses.
- Child classes can add their own unique characteristics on top of the inherited ones.
- This promotes code reusability and a hierarchical structure in software design.
