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.

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:
