Q4 define static variable also explain life time of static variable? (3)

Q5 what do you know about run time error? (3)

Q6 what are limitation of the friendship between classes? (3)

Q7: read the code and explain the functionality of this program? See page 535 for cod (3)

Date: 20-7-2013

Time: 7:00 am

Subjective:

Question 1)

class matrix                      (5 marks)

{

private:

int Elements ;

};

write insertion operator for this class..

Question 2) Create an array of 15 elements which take input from getline function till the delimiter 'comma'.

Question 3) Working of the copy constructor mentioned in the matrix which was the test subject for the last 3 lectures of cs201.

Question 4) main() {

int x= 5;

{

int x =10;

coutx;

}

coutx;

System("pause");

}

Describe the output of this program.

Question 5) main(){

int x =3, y = 4;

char b = 1, i = 0;

if ( x,y,b,i)

{

cout"Exams";

}

}

Describe the output.

Question 6) Then there was a code with a error and we had to identify and remove the error. I can not remember the code but it was regarding dangling pointers.

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)

1. Using stream insertion operator>>
2. 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)

1. What happen when we assign that object using default assignment operator?
2. What happen if we use delete one object in the above mentioned situation?
