today was my cs201 papr...thank God acha ho gya... Mcqs mostly from Moaaz file.. what will be the output of the following code snippet? Int x; Int &y=x; Y+=5; Coutx; 10 what will be out put of given program? # include Using namespace std; Int main(); { Int n; N=77; Cout.width(6); Coutrightnendl; Cout.width(6); Coutleftnendl; Retrun 0; } Read the given code and explain the code functionality? (2 Marks) Matrix :: Matrix ( int row , int col ) { numRows = row ; numCols = col ; 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 ] = 0.0 ; } } Hint : This function belong to a matrix class, having Number of Rows = numRows Number of Columns = numCols What will be the output of following function if we call this function by passing int 5? template T reciprocal(T x) {return (1/x); } object and class are same? agree or diagree ? justify your coment?? frendship of class granted or taken kuch is trah ka tha.. Long question thora tuf thy...wo yad n hn..Best of luck..

Q41: What will be the output of following code snippet? (2 Marks)
Q42: Write down the general syntax for unary operator function? (2 Marks)
Q43: Why it is meaningless to declare a static variable inside main () function? (2 Marks)
Q44: Read the given code and explain the code functionality? (2 Marks)
Matrix :: Matrix ( int row , int col )
{
numRows = row ;
numCols = col ;
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 ] = 0.0 ;
}
}
Hint : This function belong to a matrix class, having
Number of Rows = numRows
Number of Columns = numCols
Q45: Write equivalent template function for the given function? (3 Marks)
Float Celsius (float Fahrenheit)
{
Float Celsius = 0.0;
Celsius = ((Fahrenheit – 32)*5/9;
Return Celsius
}
Q46: Which one of the given two methods is better to read from a file and why? (3 Marks)
Using stream insertion operator>>
Using get() function
Q47: Identify the errors in following member operator function and also correct them? (3 Marks)
math * operator (math m)
{
math temp;
temp.number= number * number;.2
return number;
Q48: Which one (copy constructor or assignment constructor) will be called in each of the following code segment? (3 Marks)
1) Matrix m1 (m2);
2) Matrix m1, m2;
m1 = m2;
3) Matrix m1 = m2;
Q49: Write a program using do-while loop to compute and display the product of all integers from 1 to 10? (5 Marks)
Q50: Write the main function in which you have to add three integer elements in template class queue, and then call print function. After that, remove two elements from the queue. (5 Marks)
Iss ke baad ik lengthy program or code likha hoa tha due to shortage of time I can’t wrote it.
Q51: Given is the code of Date Class. (5 Marks)
Class Date
{
Private:
Int Day;
Int month;
Int year;
Public:
Date ()
{
Day = 01;
Month = 01;
Year = 2000;
}
};
Write the code for a class person which contain three data number name, and DOB, where Name and Address are char pointer while DOB (Date of Birth) is an object of type Date. This class should also contain a default constructor to initialize all its data members using same default values.
Q52: Suppose an object has a pointer type as its data member. (5 Marks)
What happen when we assign that object using default assignment operator?
What happen if we use delete one object in the above mentioned situation?

____________________
yesterday
class first:
{
public :
class second

public :
void display ()
{
cout inner object called // less thn sign hud lga lo }
} ;
} ;
write main() function to create an object of inner class and then call it's function display().
---------------------
Given is the code of a data class
class data
{
private :
int day ;
int month ;
int year ;
public :
date ()
{
day = 01 ;
month = 01 ;
year = 2000 ;
}
};
write the code for a person which contains three data members Name, Address and DOB,
where name and address are char pointers while DOB is an object of type date.
----------
class date
{
private :
int day, month, year ;
public :
date ()
{
day = 01:
month = 01 ;
year = 2000 ;
}
void display ()

cout day _ month _ year ; // mara less than sign } ;
write the code of dynamically creating the array of 10 objects of type date using loop, calll the display () function for each of the object.
-----------------
In how many ways a unary operator can be overloaded for a class , write down the discription of each way?

another paper .. Mcq's were mostly from past papers

Write two types of conversion of user-defined data type?
What is the keyword ‘this’ and what are the uses of ‘this’ pointer?
What is inline function? An ordinary function is available to us then why we use inline?
What is constructor? How we call it in our program?
Declare it as input stream or output stream. get(), getline(), put(), putline()
Which unary operator is used to measure the size of variables in user-defined data type?
Write down piece of code that will declare a matrix of 3x3. And initialize all its locations with 0;
what is the return type or data of insertion operator
