Which of the following are true for inherited operators? | If any member function is defined to be virtual, the destructor should also be defined to be virtual. | If an assignment operator is defined in the base class, then an assignment operator must be defined in the derived class. The copy constructor for the derived class automatcally calls the default constructor of the base class before it runs. Relational operators need not be defined in the derived classes if there is a virtual function that can be used to compare. All overloaded operators except the copy assignment operator(-) are inherited. 00000
