Question
Which of the following is true about base and derived classes?A base class is always smaller in size than a derived classA derived class is a specialized version of a base class.A base class is a specialized version of a derived class.A derived class cannot have its own data members.
Solution
The correct statement is: "A derived class is a specialized version of a base class."
Here's why:
-
"A base class is always smaller in size than a derived class" - This is not necessarily true. The size of a class is determined by the data members and functions it contains, not whether it is a base or derived class.
-
"A derived class is a specialized version of a base class." - This is true. In object-oriented programming, a derived class is created from a base class, but with additional attributes or functions, making it a specialized version of the base class.
-
"A base class is a specialized version of a derived class." - This is not true. It's the other way around; a derived class is a specialized version of a base class.
-
"A derived class cannot have its own data members." - This is not true. A derived class can have its own data members in addition to the ones it inherits from the base class.
