Which of the following can be facilitated by the Inheritance mechanism?

1. Use the existing functionality of base class.
2. Overrride the existing functionality of base class.
3. Implement new functionality in the derived class.
4. Implement polymorphic behaviour.
5. Implement containership.

1. A derived class object contains all the base class data.
2. Inheritance cannot suppress the base class functionality.
3. A derived class may not be able to access all the base class data.
4. Inheritance cannot extend the base class functionality.
5. In inheritance chain construction of object happens from base towards derived.

1. static
2. protected
3. private
4. shared
5. public

namespace CuriousTabConsoleApplication
{
    class Baseclass
    { 
        int i;
        public Baseclass(int ii)
        {
            i = ii;
            Console.Write("Base "); 
        } 
    } 
    class Derived : Baseclass
    {
        public Derived(int ii) : base(ii)
        {
            Console.Write("Derived ");
        } 
    } 
    class MyProgram
    { 
        static void Main(string[ ] args)
        { 
            Derived d = new Derived(10);
        } 
    } 
}

namespace CuriousTabConsoleApplication
{ 
    class Baseclass
    { 
        public void fun()
        { 
            Console.WriteLine("Hi" + " ");
        } 
        public void fun(int i)
        {
            Console.Write("Hello" + " ");
        } 
    } 
    class Derived: Baseclass
    {
        public void fun()
        {
            Console.Write("Bye" + " ");
        } 
    } 
    class MyProgram
    { 
        static void Main(string[ ] args)
        { 
            Derived d; 
            d = new Derived(); 
            d.fun(); 
            d.fun(77);
        } 
    } 
}

String s1 = "Five Star";
String s2 = "FIVE STAR";
int c;
c = s1.CompareTo(s2);
Console.WriteLine(c);

String s1, s2; 
s1 = "Hi"; 
s2 = "Hi";

1. String objects cannot be created without using new.
2. Only one object will get created.
3. s1 and s2 both will refer to the same object.
4. Two objects will get created, one pointed to by s1 and another pointed to by s2.
5. s1 and s2 are references to the same object.

String s1 = "Nagpur";
String s2;
s2 = s1.Insert(6, "Mumbai"); 
Console.WriteLine(s2);

1. String s = "123"; 
   int i;
   i = (int)s;

2. String s = "123";
   int i;
   i = int.Parse(s);

3. String s = "123"; 
   int i;
   i = Int32.Parse(s);

4. String s = "123"; 
   int i;
   i = Convert.ToInt32(s);

5. String s = "123"; 
   int i;
   i = CInt(s);
