C Sharp (C#) - Inheritance

What will be the output of this C# code?

class Animal { public void Speak() { Console.WriteLine("Animal speaks"); } } class Dog : Animal { } class Program { static void Main() { Dog d = new Dog(); d.Speak(); } }

AAnimal speaks

BDog speaks

CCompilation error

DNo output

Step-by-Step Solution

Solution:

Step 1: Understand inheritance and method call
Dog inherits from Animal but does not override Speak(), so Dog uses Animal's Speak() method.
Step 2: Predict output of d.Speak()
Calling d.Speak() prints "Animal speaks" because Dog inherits that method.
Final Answer:
Animal speaks -> Option A
Quick Check:
Inherited method output = "Animal speaks" [OK]

Quick Trick: Derived class uses base class method if not overridden [OK]

Common Mistakes:

MISTAKES

Expecting Dog to print "Dog speaks" without override
Thinking code causes compilation error
