    Study Notes

    Inheritance in Object-Oriented Programming

    • When a child object is created through inheritance, the exception is that it automatically inherits all the properties and behavior of the parent object.
    • Inheritance allows programmers to create a new class that is a modified version of an existing class, enabling code reuse and a more hierarchical organization of code.

    Types of Classes in Inheritance

    • A class that is inherited from another class is called a subclass or derived class.
    • The parent class from which the subclass is inherited is called the superclass or base class.

    Prototype-Based Inheritance

    • This type of inheritance involves creating objects that are instances of other objects, rather than instances of classes.

    Inheritance Relationships

    • The relationships between objects or classes through inheritance give rise to a directed acyclic graph (DAG).

    CBSE Class 8 Science Syllabus

    • The purpose of the CBSE Class 8 Science Syllabus is to provide a structured framework for teaching and learning science.
    • Referring to the CBSE Syllabus for Class 8 Science is important for students to understand the learning objectives, assessment criteria, and weightage of each unit.
    • Knowing the weightage of each unit in the Science syllabus helps students prioritize their study time and focus on the most important topics.
    • The CBSE Class 8 Syllabus for 2023-24 covers various topics in physics, chemistry, and biology, including concepts, experiments, and project work.
    • Students must study the chapters provided in the NCERT Class 8 Science textbook to gain a comprehensive understanding of the subject and prepare for assessments.
