Please Share your Current Papers Questions/Pattern here to help each other. Thanks

My today papers is

Total questions is 54 and 40 mcqs

4 questions of 2 marks

4 questions of 3 marks

4 questions of 5 marks

mostly mcqs from past papers and the long questions about classes and friendship mcqs pooranay aye thay...

75% paper mein template per hi baat hoi
15% classes n inheritance tha
aur baki ka 10 % mix mein se tha...

so templates ko mostly prepare karen.

Long Question

Q1: Given is the code for a class named Coordinate.(10)

class Coordinate
{

private:

int X, Y;

public:

Coordinate()
{
X = 0;
Y = 0;

class Coordinate
{
friend void Displaycord();
private:

int X, Y;

public:

Coordinate()
{
X = 0;
Y = 0;

};

Q2: Write a program that defines a Template function named Square () which finds the square of a number and then return it. Define one variable of type int in main function and then call Square function on that. (10)

Program output should look like this:

Enter an integer value to find its Square: 6
Square of integer number is: 36

Q3: Why is it necessary to initialize a static object as the time of creation and how it is initialized ?(5)

Q4:Transform the following If-else statement into switch statement.(5)

if (x == 5)
...
else if (x == 10 || x == 11)
...
else if (x == 8)
...
else if (x == 9)
...
else
...

Q5:Read the given code and explain code functionality. (3)

Matrix :: Matrix ( const Matrix & m )
{
numRows = m.numRows ;
numCols = m.numCols ;
elements = new ( double * ) [ numRows ] ;
for ( int i = 0 ; i < numRows ; i ++ )
{
elements [ i ] = new double [ numCols ] ;
for ( int j = 0 ; j < numCols ; j ++ )
elements [ i ] [ j ] = m.elements [ i ] [ j ] ;
}
}

Hint : This function belong to a matrix class, having
Number of Rows = numRows
Number of Columns = numCols

Q6: In the following code;(3)

#include <iostream.h>
#include <conio.h>
main() {

double j;

getche();

}

Is double j; an example of global variable or local variable ? Why ?

Q7: Identify and correct the error in the given code segment.(3)
main()
{
int val = 30;
int &ref = val;

&ref = &ref++;

}

Q8: Determine the output of the given program code.(2)

for (int I = 1; i<5; i++){
if ( I == 3)
continue;
cout I endl ;
}

Q9: What is the output of following code snippet.(2)

// class templates
#include <iostream>
using namespace std;

template <class T>
class mypair {
T a, b;
public:
mypair (T first, T second)
{a=first; b=second;}
T getmax ();
};

template <class T>
T mypair<T>::getmax ()
{
T retval;
retval = a>b? a : b;
return retval;
}
int main () {
mypair <int> myobject (100, 75);
cout myobject.getmax();
system("pause");
}

Q10: How can we declare and initialize static data member of a class?(2)

Q11: When memory is allocated dynamically using new operator within the constructor of class then what is an appropriate place to de-allocate the memory?(2)

Q11: Write down the output of the following code segment? (2)

int x = {0,1, 2, 3, 4, 5, 6, 7, 8, 9};
int *xptr;
xptr = &x;
cout *(xptr++) + 1;
