What is NOT true about the 'virtual' keyword in C++?

It forces a function to be implemented in derived classes
It enables late binding for the function
It is only required in the base class declaration
Derived class functions matching the base class declaration are treated as virtual

The correct answer is: It forces a function to be implemented in derived classes

Using the 'virtual' keyword in C++ does not force a function to be implemented in derived classes. Instead, it allows for dynamic binding at run-time and enables polymorphism. Option B is incorrect because the 'virtual' keyword does enable late binding. Option C is incorrect because the 'virtual' keyword is required in both the base class declaration and the derived class declaration. Option D is incorrect because the function in the derived class must also be declared as 'virtual' to be treated as such.
