The function that would be overridden is preceded by the virtual keyword in the base class. This happens during compilation, which is why it is also known as compile time polymorphism. (b) Overloading does not block inheritance from the superclass whereas overriding blocks inheritance from the superclass. Above is an example of how doSomething() can be overloaded as a free standing function and as a method/member function.
