Give a definition for a class SmartBut that is a derived class of the base class Smart given in the following. Do not bother with # include directives or namespace details. class Smart {
public: Smart ( );
void printAnswer ( ) const;
protected: int a; int b; };
This class should have an additional data field, crazy, of type bool; one additional member function that takes no arguments and returns a value of type bool; and suitable constructors. The new function is named iscrazy. You do not need to give any implementations, just the class definition.
