2 An abstract class
|
can always be instantiated as an object |
||
|
can sometimes be instantiated as an object |
||
|
can often be instantiated as an object |
||
|
can never be instantiated as an object |
3)When a derived class defines a member method that has the same name, parameters, and return type as a base class's method, the member method is said to
|
overload the base class's method |
||
|
overreach the base class's method |
||
|
override the base class's method |
||
|
overshadow the base class's method |
