The following few questions involved the classes diagrammed below:

Parent Class

Subclass

Subclass

Class Parent

virtual void foo();
virtual void bar() = 0;
void func1();
protected:
int ParentProtected;
private:
double ParentPrivate;
};

Class Child

void foo( );
void func2();
virtual void bar();
protected:
int ChildProtected;

};

Class GrandChild

virtual void bar();
virtual void foobar();
private:
int GrandChildPrivate;

};

Based on the classes shown above, the next few questions relate to the following declarations shown below:

Child instanceofChild;
Child * ptrChild = &instanceofChild;
GrandChild instanceofGChild;
GrandChild * ptrGrandChild = &instanceofGChild;

1. The keyword friend on a method appears in the: .h file .cpp file 2. The keyword const on a class method appears in the: .h file .cpp file 3. The keyword const on a class method parameter appears in the: .h file .cpp file 4. The keyword virtual applied to a class method appears in the: .h file .cpp file 5. Unless implemented by the class author to do something different, a copy-constructor performs member-wise copying of the member variables in a class. True False 6. A copy constructor gets invoked whenever a class method returns a classtype variable. True False 7. If marked as friend, can the overloaded operator>> also be marked as aconst method of a class? Yes No 8. If marked as friend, can the overloaded operator- also be marked as aconst method of a class? Yes No 9. If marked as friend, can the overloaded operator< also be marked as aconst method? Yes No 10. Once a method is marked virtual in a class hierarchy, every other version of that method in all of its subclasses will also be treated asvirtual . True False
