Which of the following is the correct way to create an object of the class Sample?

1. Sample s = new Sample();
2. Sample s;
3. Sample s; s = new Sample();
4. s = new Sample();

namespace CuriousTabConsoleApplication
{ 
    class Sample
    { 
        int i, j; 
        public void SetData(int ii, int jj)
        {
            this.i = ii;
            this.j = jj 
        } 
    } 
    class MyProgram
    { 
        static void Main(string[ ] args)
        { 
            Sample s1 = new Sample(); 
            s1.SetData(10, 2); 
            Sample s2 = new Sample(); 
            s2.SetData(5, 10); 
        } 
    } 
}

int i;
int j = new int();
i = 10;
j = 20; 
String str; 
str = i.ToString(); 
str = j.ToString();

1. Data members ofa class are by default public.
2. Data members of a class are by default private.
3. Member functions of a class are by default public.
4. A private function of a class can access a public function within the same class.
5. Member function of a class are by default private.

class Sample
{
    private int i;
    public Single j;
    private void DisplayData()
    {
        Console.WriteLine(i + " " + j);
    }
    public void ShowData()
    {
        Console.WriteLine(i + " " + j);
    }
}

1. All objects of Sample class will always have exactly same data.
2. Objects of Sample class may have same or different data.
3. Whether objects of Sample class will have same or different data depends upon a Project Setting made in Visual Studio.NET.
4. Conceptually, each object of Sample class will have instance data and instance member functions of the Sample class.
5. All objects of Sample class will share one copy of member functions.

sample c;
c = new sample();

1. It will create an object called sample.
2. It will create a nameless object of the type sample.
3. It will create an object of the type sample on the stack.
4. It will create a reference c on the stack and an object of the type sample on the heap.
5. It will create an object of the type sample either on the heap or on the stack depending on the size of the object.

namespace CuriousTabConsoleApplication
{ 
    class Sample
    { 
        int i; 
        Single j; 
        public void SetData(int i, Single j)
        { 
            this.i = i; 
            this.j = j;
        }
        public void Display()
        { 
            Console.WriteLine(i + " " + j);
        } 
    } 
    class MyProgram
    { 
        static void Main(string[ ] args)
        {
            Sample s1 = new Sample(); 
            s1.SetData(36, 5.4f); 
            s1.Display(); 
        } 
    } 
}
