What is encapsulation in C++?

• Hiding the internal details and showing only the functionality

• Creating multiple functions with the same name

• Inheriting properties from another class

How can you achieve encapsulation in C++?

What is abstraction in C++?

• Overloading operators to work with user-defined data types

How is abstraction typically implemented in C++?

• Through the use of access specifiers

• By using abstract classes and interfaces

• By allocating memory dynamically

• Through the use of global variables
