C++ :: Overriding Inherited Virtual Functions

Is it possible to do something like this:

class A //parent {
public:
virtual void DoSomething() = 0;
};

class B : public A //child {
public:
void DoSomething(string s) override;
}

Where the child member function overrides and changes the parents member function.

I need to pass an array of key states to the Controller class' Update() function but don't want to send it to every class derived from Object (like Controller).

Is this possible or do I have to overload the original Update() member function (but I would need to define the method in Object then (i.e remove the pure virtual function (=0)))
