There are 5 types of Inheritance in C++: Single inheritance Multiple inheritance Hierarchical inheritance Multilevel inheritance Hybrid inheritance Single Inheritance: A class derives from only one base class in single inheritance. This means that there is only one subclass descended from a single superclass. Syntax: Example: Output: Multiple inheritance: Multiple inheritance is a type of […]

Inheritance refers to a class’s ability to derive properties and characteristics from another class. One of the most important aspects of Object-Oriented Programming is inheritance. This also allows: Code reusability Quick implementation time Runtime polymorphism In inheritance, there are two kinds of classes: A parent class, also known as a base class, is a class whose […]

Object-oriented programming (OOPs) is a programming approach or pattern in which programs are structured around objects rather than functions and logic. It partitions the data into two memory areas, namely data and functions, and aids in making the code flexible and modular. Concepts of an Object-Oriented Programming language: There are some basic concepts that act […]

Association: Association is a relation between two separate classes which establishes through their Objects. One-to-one, one-to-many, many-to-one, and many-to-many associations are all possible. An Object communicates with another object to use its functionality and services in Object-Oriented programming. Composition and Aggregation are the two forms of association. Composition: The strongest type of association is composition. It represents part-of relationship. If […]

In Java, inheritance is a mechanism by which one object inherits all of its parent’s properties and behaviors. It is an essential component of OOPs (Object-Oriented programming systems). You can use the parent class’s methods and fields when you inherit from an existing class. You can also add new methods and fields to your current […]
