T[25][30] is a two dimensional array, which is stored in the memory along the row with each of its element occupying 2 bytes, find the address of the element T[10][15], if the element T[5][10] is stored at the memory location 25000.

Write the definition of a member function ADDMEM() for a class QUEUE in C++, to add a MEMBER in a dynamically allocated Queue of Members considering the following code is already written as a part of the program.

struct Member
{
	int MNO;
	char MNAME[20];
	Member *Next; 
};
class QUEUE
{
	Member *Rear,*Front;
public:
	QUEUE(){Rear=NULL;Front=NULL;}
	void ADDMEM();
	void REMOVEMEM();
	~QUEUE();
};

T[20][50] is a two dimensional array, which is stored in the memory along the row with each of its element occupying 4 bytes, find the address of the element T[15][5], if the element T[10][8] is stored at the memory location 52000.

Write the definition of a member function INSERT() for a class QUEUE in C++, to insert an ITEM in a dynamically allocated Queue of items considering the following code is already written as a part of the program.

struct ITEM
{
	int INO; char INAME[20];
	ITEM *Link;
};
class QUEUE
{
	ITEM *R,*F;
	public :
	QUEUE() {R=NULL;F=NULL;}
	void INSERT();
	void DELETE();
	~QUEUE();
};

Write a definition for a function SHOWMID (int P[][5], int R, int C) in C++ to display the elements of the middle row and middle column from a two-dimensional array P having R number of rows and C number of columns. For example, if the content of the array is as follows:

The function should display the following as output :
103 101 121 102 101
116 121 109

A two-dimensional array P[20] [50] is stored in the memory along the row with each of its element occupying 4 bytes, find the address of the element [10] [30], if the element P[5] [5] is stored at the memory location 15000.

Write the definition of a member function Pop() in C++, to delete a book from a dynamic stack of TEXTBOOKS considering the following code is already included in the program.

struct TEXTBOOKS
{
	char ISBN[20]; char TITLE[80];
	TEXTBOOKS *Link;
};
class STACK
{
	TEXTBOOKS *Top;
public:
	STACK(){Top=NULL;}
	void Push();
	void Pop();
	~STACK();
};

Write a function REVCOL (int P[] [5], int N, int M) in C++ to display the content of a two-dimensional array, with each column content in reverse order.

Note: Array may contain any number of rows.

For example, if the content of the array is as follows:

The function should display output as:

Write a function ALTERNATE (int A[][3],int N,int M) in C++ to display all alternate element from two-dimensional array A (starting from A[0][0]).
For example:
If the array is containing:

The output will be:
