The AeroCar class inherits from the Car class. For the AeroCar class to override the set_speed function, what must be done?

• i believe this is c++ we're talking about.

• Yes, we are.We can even override a non virtual method.

• no, you can't. you can hide a non virtual method in a subclass, which is different because c++ is hide by name.
  
  example:
  class foo {
  public:
  int f(int x) {return 1;}
  };
  class bar: public foo {
  public:
  int f(const char* v) {return 2;}
  };
  
  if you have a bar and try to call f with an integer, you'll get an error. because bar::f(const char*) has hidden foo:f(int) because they have the same name (that is type is irrelevant). this is altogether different from overriding a method, imho.
  
  c++ has no "override" keyword anyway.

• I think you are right.I just checked it.I was thinking in terms of C#.
