Search Results
Correct Answer: True
Correct Answer: True
Correct Answer: True
Explanation:
This is because the member functions are always searched in the derived class and then in the base class.
Correct Answer: Classes and Methods
Correct Answer: 4, 5
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
Explanation:
We can derive from a base class even if it is present in an assembly.
Correct Answer: False
Explanation:
Base class cannot access derived class members since it does not have any knowledge of the derived class.
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().
