Long Question

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

class Coordinate


int X, Y;


X = 0;
Y = 0;

class Coordinate
friend void Displaycord();

int X, Y;


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)

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)

main() {

double j;



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

Q7: Identify and correct the error in the given code segment.(3)
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)
cout I endl ;

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

// class templates
using namespace std;

class mypair {
T a, b;
mypair (T first, T second)
{a=first; b=second;}
T getmax ();

T mypair::getmax ()
T retval;
retval = a>b? a : b;
return retval;
int main () {
mypair myobject (100, 75);
cout myobject.getmax();

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[10] = {0,1, 2, 3, 4, 5, 6, 7, 8, 9};
int *xptr;
xptr = &x[5];
cout *(xptr++) + 1;

When an object of a class is defined inside another class then ______________.
Every stream has _________.
_________in the following options is not a method of output stream.
To perform manipulation with input/output, we have to include ________ header file
A class whose object is contained as const object, must have ____________.
By using objects as class members, _________ is achieved
The operator function will be implemented as _____, if both objects (obj1, obj2) are passed as arguments to - operator in the statement given below.
obj3 = obj1 - obj2;

ANSI stands for _________.
A template function must have at least _______________ generic data type.

Which of the following is true about operator overloading?
1-The operator works with only objects of the class in which it is overloaded.
2-The operator works with objects and primitive data types regardless of parameters.
3-The operator works with both objects and primitive data types depending on parameters.
4-The operator must have a constant and an object as parameters.
Operator overloading can be performed through__________________.
The pointer returned by the new operator points to ___________ of memory chunks allocated by the new operator.

The return type of the operator function for operator is __________.

What will be the output of following statement?

cout setfill(‘0’) setw(7) 128 ;

The operator used for casting in C is standard ________ operator.

Consider the following code segment.

struct intorDouble
Int ival;
Double charvar;

intorDouble VAZ;
int size ;
size = sizeof(VAZ);

What will be the value of variable size if integer occupies 4 bytes and double occupies 8 bytes?

The file-open mode __________ is used to open a file for output and move to the end of the file.

In the statement int &x = y; compiler ______.
Which header file must be included to use the functions tolower() and toupper()?
Which one of the following functions is included in stdlib.h header file?
For one byte, there are _____ combinations of values which can be stored in computer.
