Write the definition of a function Reverse(int Arr[], int N) in C++, which should reverse the entire content of the array Arr having N elements, without using any other array.

Example: if the array Arr contains

13

10

15

20

5

Then the array should become

5

20

15

10

13

NOTE:

• The function should only rearrange the content of the array.
• The function should not copy the reversed content in another array.
• The function should not display the content of the array.

Answer the questions (i) to (iv) based on the following:

class One
{
	int A1;
protected:
	float A2;
public:
	One();
	void Get1(); void Show1();
};

class Two :
private One
{
	int B1;
protected:
	float B2;
public:
	Two();
	void Get2();
	void Show();
};

class Three : public Two
{
	int C1;
public:
	Three();
	void Get3();
	void Show();
};
void main()
{
Three T;		//Statement 1
_______;		//Statement 2
}

(i) Which type of Inheritance out of the following is illustrated in the above example?
-Single Level Inheritance, Multilevel Inheritance, Multiple Inheritance.

(ii) Write the names of all the member functions, which are directly accessible by the
object T of class Three as declared in main() function.

(iii) Write Statement 2 to call function Show() of class Two from the object T of Class Three.

(iv) What will be the order of execution of the constructors, when the object T of
class Three is declared inside main()?

}
TEST(TEST &T)      //Member Function 2
{
	TCode=E.TCode+1;

	Score=T.Score;
}
};
void main()
{
_________________	//Statement 1
