2. 

Which of the following statements should be added to the subroutine fun( ) if the C#.NET code snippet given below is to output 9 13?

class BaseClass
{
    protected int i = 13;
}
class Derived: BaseClass
{
    int i = 9; 
    public void fun()
    {
        // [*** Add statement here ***]
    } 
}

A. Console.WriteLine(base.i + " " + i);
B. Console.WriteLine(i + " " + base.i);
C. Console.WriteLine(mybase.i + " " + i);
D. Console.WriteLine(i + " " + mybase.i);
E. Console.WriteLine(i + " " + this.i);

3. 

Which of the following statements are correct about the C#.NET code snippet given below?

namespace IndiabixConsoleApplication
{ 
    class index
    {
        protected int count;
        public index()
        {
            count = 0;
        }
    }
    class index1: index
    {
        public void increment()
        {
            count = count +1;
        }
    }
    class MyProgram
    {
        static void Main(string[] args)
        {
            index1 i = new index1(); 
            i.increment(); 
        }
    }
}
  1. count should be declared as public if it is to become available in the inheritance chain.
  2. count should be declared as protected if it is to become available in the inheritance chain.
  3. While constructing an object referred to by i firstly constructor of index class will be called followed by constructor of index1 class.
  4. Constructor of index class does not get inherited in index1 class.
  5. count should be declared as Friend if it is to become available in the inheritance chain.

A. 1, 2, 5
B. 2, 3, 4
C. 3, 5
D. 4, 5
