(2 Points)
a) To prevent the function from being overridden in derived classes.
b) To mark the function as static.
c) To mark the function as deprecated.
d) To make the function a template.
Solution
The purpose of using the final keyword with a virtual function is:
a) To prevent the function from being overridden in derived classes.
The final keyword in C++ is used to restrict the users from overriding the virtual function in the derived class. This means that if a function is declared as final then it cannot be overridden in any of the inheriting classes. This is useful when you want to maintain the original functionality of a function in all derived classes without any modification.
