• It involves encapsulation, inheritance, and polymorphism.

• Encapsulation is the process of hiding implementation details from the user.

• Inheritance allows a class to inherit properties and methods from another class.

• Polymorphism allows objects to take on multiple forms or behaviors.

• Examples of O

A blueprint for creating objects that share common properties and behaviors.

• Classes are used in object-oriented programming to create objects with similar attributes and methods.

• They serve as a blueprint for creating objects.

• Classes can inherit properties and methods from other classes.

• Examples include a class for creating different types of cars or a class for creating different types of animals.

Abstraction is the process of hiding complex implementation details and exposing only the necessary information.

• It helps to reduce complexity and increase efficiency in software development.

• For example, a car dashboard abstracts away the complex workings of the engine and presents only the...read more

Object slicing is when a derived class object is assigned to a base class object, resulting in loss of derived class attributes.

• Object slicing occurs when a derived class object is assigned to a base class object.

• The result is the loss of derived class attributes.

• This happens because the base class object can only hold the attributes of the base class.

• Example: class Base { int x; }; class Derived : public Base { int y;...read more
