C++ Structures vs Classes Quiz

What is the main topic of this tutorial?

• Introduction to C++

• Structures vs Classes in C++

• Advanced C++ Programming

• C++ for Beginners

Which of the following is true about structures in C++?

• Structures are private by default.

• Structures are meant for object-oriented programming.

• Structures cannot have member functions.

• Structures are public by default.

What is the default access specifier for classes in C++?

• Internal

• Protected

• Private

• Public

How can structures be used in C++?

• To group items of different types into a single type

• To create a single data type

• To implement inheritance

• To define private methods

What is a key similarity between structures and classes in C++?

• Both are private by default

• Both can have constructors

• Both cannot have member functions

• Both are used for procedural programming

In the code example, what error occurs when trying to access a private member?

• Compilation error

• Access violation error

• Runtime error

• Syntax error

What must be done to access private members of a class in C++?

• Use a reference

• Use a pointer

• Declare them as public

• Use a friend function

What is the purpose of constructors in C++?

• To allocate memory

• To destroy objects

• To define object behavior

• To initialize objects

Why is it unconventional to use object functions in structures?

• Because structures are not meant for object-oriented programming

• Because structures cannot have functions

• Because it is not supported by the compiler

• Because it leads to syntax errors

What is the main takeaway about structures in C++?

• They are primarily used for procedural programming

• They are similar to classes but with different default access

• They cannot be used in modern C++

• They are designed for object-oriented programming
