b. :
c. #
d. !!$

Show Answer

The correct option is (a)

6. Which other keywords are also used to declare the class other than class ?

a. union
b. object.
c. both struct & union
d. struct

Show Answer

The correct option is (d)

b. public & protected
c. protected
d. private

Show Answer

The correct option is (d)
Explanation:
By default all the data members and member functions of class are private.
