If the array is 1, 2, 3, 4, 5, 6 If the array is 1, 2, 3The resultant 2 D array is given below The resultant 2 D array is given below

1 2 3 4 5 6 1 2 31 2 3 4 5 0 1 2 01 2 3 4 0 0 1 0 01 2 3 0 0 01 2 0 0 0 0

1 0 0 0 0 0

(b) An array MAT[30][10] is stored in the memory column wise with each elementoccupying 8 bytes of memory. Find out the base address and the address of elementMAT[20][5], if the location of MAT[5][7] is stored at the address 1000.

(c)class queue{ int data[10];

int front, rear;public:

queue() { front =-1; rear =-1; }void add(); // to add an element into the queuevoid remove(); // to remove an element from the queuevoid Delete(int ITEM); // to delete all elements which are equal to ITEM

};

Complete the class with all function definitions for a circular array Queue. Use anotherqueue to transfer data temporarily.

(d) Write a function in C++to perform a PUSH operation on a dynamically allocatedstack containing real number.

(e) Write the equivalent infix expression for : a, b, AND, a, c, AND, OR

CBSE 20058. (a) Write a function in C++which accepts an integer array and its size as arguments/

parameters and exchanges the value of first half side elements with the second half sideelements of the array.Example:

If an array of eight elements has initial content2, 4, 1, 6, 7, 9, 23, 10

The function should rearrange the array as7, 9, 23, 10, 2, 4, 1, 6

(b) An array Arr[15][35] is stored in the memory along the column with each of itselements occupying 8 bytes. Find out the base address and the address of an elementArr[2][5], if the location Arr[5][10] is stored at the address 4000.

(c) Write a function in C++to perform a PUSH operation in dynamically allocatedstack considering the following:

struct Node{

int X, Y ;Node *Link;

};

class STACK{

Node * Top;public:

STACK() { Top =NULL; }

void PUSH();void POP();~STACK();

};

(d) Write a function in C++ to print the sum of all the values which are eitherdivisible by 2 or are divisible by 3 present in a two dimensional array passed as theargument to the function.

(e) Evaluate the following postfix notation of expression:10, 20, +, 25, 15, -, *, 30, /

CBSE 20049. (a) Define a function Reversearray ( int [ ], int), that would accept a one dimensionalinteger array NUMBERS and its size N. The function should reverse the contents of arraywithout using any second array.Note: Use the concept of swapping elements (If the array initially contains)

{ 2, 15, 3, 14, 7, 9, 19, 6, 1, 10 } then after reversal the array should contain{ 10, 1, 6, 19, 9, 7, 14, 3, 15, 2 }

(b) An array ARR[5][5] is stored in the memory with each element occupying 4 bytes

of space. Assuming the base address of ARR to be 1000, compute the address ofARR[2][4], when the array is stored:(i) Row Wise (ii) Column Wise

(c) Write a function in C++to find and display the sum of each row and each columnof a 2 dimensional array of type float.

(d) Evaluate the following Postfix notation of expression, show status of stack foreach operation: 500, 20, 30, +, 10, *, +(e) Define functions stackpush() to insert nodes and stackpop() to delete nodes, for alinked list implemented stack having the following structure for each node:

struct node{ char name[20]; int age;

node *Link;};class stack{ node *top;

public:
