C Sharp (C#) - Inheritance

Consider the following code:

class Parent {
    protected int number = 5;
}

class Child : Parent {
    public int GetNumber() {
        return number;
    }
}

class Program {
    static void Main() {
        Child c = new Child();
        Console.WriteLine(c.GetNumber());
    }
}

What will be the output when this program runs?

A0

B5

CCompilation error

DRuntime error

Step-by-Step Solution

Solution:

Step 1: Understand protected member access in subclass
The number field is protected, so the subclass Child can access it directly.
Step 2: Trace the program output
The GetNumber method returns number which is 5, so Console.WriteLine prints 5.
Final Answer:
5 -> Option B
Quick Check:
Protected field accessed in subclass = 5 [OK]
