What will be the output of the following C# code snippet?
class B { } class A : B { } class Program { static void Main(string[] args) { A a = new A(); B b = new B(); if (a is A) Console.WriteLine("a is an A"); if (b is A) Console.WriteLine("b is an A because it is derived from A"); if (a is B) Console.WriteLine("This won’t display -- a not derived from B"); Console.ReadLine(); } }
a is an A This won’t display -- a not derived from B
a is an A b is an A because it is derived from A
b is an A because it is derived from A This won’t display -- a not derived from B
"Both ""a is an A This won’t display — a not derived from B"" & ""a is an A b is an A because it is derived from A"""
