- Question
The way a derived class member function can access base class public members, the base class member functions can access public member functions of derived class.
Options- A. True
- B. False
- Correct Answer
- False
ExplanationBase class cannot access derived class members since it does not have any knowledge of the derived class. - 1. We can derive a class from a base class even if the base class's source code is not available.
Options- A. True
- B. False Discuss
- 2. Multiple inheritance is different from multiple levels of inheritance.
Options- A. True
- B. False Discuss
- 3. The size of a derived class object is equal to the sum of sizes of data members in base class and the derived class.
Options- A. True
- B. False Discuss
- 4. There is no multiple inheritance in C#.NET. That is, a class cannot be derived from multiple base classes.
Options- A. True
- B. False Discuss
- 5. Private members of base class cannot be accessed by derived class member functions or objects of derived class.
Options- A. True
- B. False Discuss
- 6. It is illegal to make objects of one class as members of another class.
Options- A. True
- B. False Discuss
- 7. If a base class contains a member function func(), and a derived class does not contain a function with this name, an object of the derived class cannot access func().
Options- A. True
- B. False Discuss
- 8. There is no private or protected inheritance in C#.NET.
Options- A. True
- B. False Discuss
- 9. Creating a derived class from a base class requires fundamental changes to the base class.
Options- A. True
- B. False Discuss

Correct Answer: True
Explanation:
We can derive from a base class even if it is present in an assembly.
Correct Answer: True
Explanation:
Multiple inheritance means deriving a class from more than one classes. On the other hand, multiple levels of inheritance means a class has been derived from a base class and the base class itself has been derived from another base class. Multiple inheritance is not permitted in C#.NET.
Correct Answer: True
Correct Answer: True
Correct Answer: True
Correct Answer: True
Correct Answer: False
Explanation:
It depends upon how the function
func() has been defined in the base class. If the function
func() is defined public in base class then an object of the derived class can access the function
func().
Correct Answer: True
Correct Answer: False
Correct Answer: True
Explanation:
This is known as multiple levels of inheritance.
