Complete Modern C++ - Project - Part VII (override and final specifier)

The video tutorial explains new C-11 keywords related to inheritance, focusing on 'final' and 'override'. It highlights the importance of marking functions as virtual for customization and preventing memory leaks. The 'final' keyword is used to prevent inheritance, while 'override' ensures correct function overriding. Practical examples demonstrate how these keywords help avoid bugs and improve code robustness. The tutorial encourages using C-11 features for better coding practices.

Why can't the functions in the 'zip' class be customized through inheritance?

• They are not marked as virtual.

• They are marked as private.

• They are overloaded functions.

• They are static functions.

What issue might arise if a class with a non-virtual destructor is inherited?

• Memory or resource leaks may occur.

• The base class destructor might not be called.

• The child class destructor will be called twice.

• The child class cannot be instantiated.

What does the 'final' keyword do when applied to a class?

• It prevents the class from being inherited.

• It makes the class abstract.

• It allows multiple inheritance.

• It makes all functions in the class virtual.

What is the purpose of the 'override' keyword in C++11?

• To declare a function as static.

• To make a function virtual.

• To prevent a function from being inherited.

• To ensure a function is overriding a base class function.

What happens if the 'override' keyword is used but the function does not match any base class function?

• The function will be ignored.

• The program will crash.

• The function will become virtual.

• A compiler error will occur.

How can you prevent a function from being overridden in derived classes?

• By using the 'final' keyword with 'override'.

• By marking it as static.

• By using the 'const' keyword.

• By declaring it as private.

What is a benefit of using C++11 features like 'final' and 'override'?

• They allow for dynamic memory allocation.

• They help write more robust and error-free code.

• They simplify the syntax of the language.

• They make the code run faster.
