Question

In C# ____________________

(a) Non – virtual or static methods can’t be overridden

(b) Non – virtual and static methods only can be overridden

(c) Overriding is not allowed

(d) Overriding must be implemented using C++ code only

The question was posed to me in an interview for internship.

This intriguing question comes from Overriding Member Functions topic in section Member Functions & its Types of Object Oriented Programming

Answer 1

Right choice is (a) Non – virtual or static methods can’t be overridden

Easiest explanation - The non-virtual and static methods can’t be overridden in C# language. The restriction is made from the language implicitly. Only the methods that are abstract, virtual or override can be overridden.
