}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.

{
public int index;
public int[] arr = new int[10];
public void fun(int i, int val)
{
arr[i] = val;

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.
int i;
int j = new int();
i = 10;
j = 20;
String str;
str = i.ToString();
str = j.ToString();1. this reference can be modified in the instance member function of a class.
2. Static functions of a class never receive the this reference.
3. Instance member functions of a class always receive a this reference.
4. this reference continues to exist even after control returns from an instance member function.
5 .While calling an instance member function we are not required to pass the this reference explicitly.
