Multiple Choice

What is encapsulation in object-oriented programming?

Encapsulation is the bundling of data and methods that operate on that data within a single unit, restricting access to some components.

Encapsulation refers to the process of inheriting properties from another class.

Encapsulation is the separation of data and methods into different classes.

Encapsulation is the practice of exposing all data and methods to the public.

Multiple Choice

What is an accessor function?

An accessor function is a type of data structure.

An accessor function modifies an object's property value.

An accessor function is a method that retrieves the value of an object's property.

An accessor function is a method that deletes an object's property.

Multiple Choice

Which keyword ensures that a member function cannot modify any data members of the class?

override

const

virtual

static

Multiple Choice

What is the main benefit of using accessor and mutator functions?

They promote data encapsulation and integrity by controlling access to an object's properties.

They simplify code by removing the need for direct property access.

They allow for multiple inheritance in object-oriented programming.

They enhance performance by reducing the number of function calls.

Multiple Choice

What is the main benefit of postfix expressions?

Elimination of parentheses and easier evaluation.

Reduction of computational efficiency and speed.

More reliance on operator precedence rules.

Increased complexity and slower evaluation.
