Day 15 Assessment -Encapsulation & Abstraction, Exception-28June

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

• Allocating memory for objects

How can you achieve encapsulation in C++?

• By using classes and access specifiers

• By using only global variables

• By writing functions outside of classes

• By using pointers

Which access specifier restricts access to the members of a class only to functions within the same class?

• public

• protected

• private

• static

What is abstraction in C++?

• Using derived classes to extend base class functionality

• Providing only essential information and hiding the background details

• Allocating dynamic memory for objects

• 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

What is the purpose of exception handling in C++?

• To write efficient code

• To handle runtime errors gracefully

• To manage memory allocation

• To create multiple threads

Which keyword is used to throw an exception in C++?

• catch

• throw

• try

• finally

Which block is used to handle exceptions in C++?

• try

• catch

• finally

• throw

What will happen if an exception is thrown but not caught in C++?

• The program will terminate abruptly

• The exception will be ignored

• The program will enter an infinite loop

• The exception will be automatically handled by the system

What does the what() member function of the exception class do?

• Returns a string describing the error

• Terminates the program

• Rethrows the exception

• Catches the exception
