XII B (CS)

1). What is the difference between call by reference and call by value with respect to memory allocation ? Give a suitable example to illustrate using C++.

2). Define a class Competition in C++ with the following descriptions:

Data Members:

Event_no integer

Description char(30)

Score integer

qualified char

Member functions:

- A constructor to assign initial values Event_No number as 101, Description as “State level”, Score is 50 and qualified as ‘N’.

- Input(), To take the input for event_no, description and score.

-Award(int), To award qualified as ‘Y’, if score is more than the

cutoffscore passed as argument to the function else ‘N’.

-Show(), To display all the details.

3). Obtain output from following program after including the desired header files.

int main( )

{

int array [ ]={ 2, 3, 5, 6};

int *arptr = array;

int value =*arptr;

 cout<<value<<'\t';

value = *arptr++;

 cout << value <<'\t';

value = *arptr;

 cout << value <<'\t';

value = * ++arptr;

 cout<<value<<'\t';

getch();

return 0;

}

4). Obtain output from following program after including the desired header files.

 

int main( )

{

char *Text = "AJANTA";

int *p, array[ ]={ 5,6,8,20};

p=array;

 cout<<*p<<'\t'<<Text<<endl;

Text++;

p++;

 cout<<*p<<'\t'<<Text<<endl;

getch();

return 0;

}

5). Obtain output from following program after including the desired header files.

int main ( )

{

int Track [ ] = {10, 20, 30, 40}, *Striker ;

Stxiker=Track :

Track [1] += 30 ;

 cout<<"Striker>"<<*Striker<<end1 ;

Striker – =10 ;

Striker++ ;

 cout<<"Next@"<<*Striker<<end1 ;

Striker+=2 ;

 cout<<"Last@"<<*Striker<<end1 ;

 cout<< "Reset To" <<Track[0] <<end1 ;

return 0;

}

7).  Obtain output from following program after including the desired header files.

int main ( )

{

int *Queen, Moves [ ] = {11, 22, 33, 44};

Queen = Moves;

Moves [2] + = 22;

 Cout<< "Queen @"<<*Queen<<end1;

*Queen - = 11;

Queen + = 2;

 cout<< "Now @"<<*Queen<<end1;

Queen++;

 cout<< "Finally@"<<*Queen«end1;

 cout<< "New Origin @"<<Moves[0]<<end1;

return 0;

}

8).  Obtain output from following program after including the desired header files.

int main()

{

char C1 ='A';

char C2 ='D';

char *i, *j;

i = &C1;

j = &C2;

i = j;

 cout << *i;

getch();

return 0;

}

9). Find the output of the following program:

#include<iostream.h>

void Indirect(int Temp=20)

{

   for(int I=10;I<=Temp;I+=5)

   cout<<I<<”,”;

   cout<<endl;

}

void Direct(int &Num)

{

   Num+=10;

   Indirect(Num);

}

int main( )

{

  int Number=20;

  Direct(Number);

  Indirect( );

  cout<<”Number =”<<Number<<endl;

return 0;

}

10). How is &p different from *p ?

11). Identify the syntax error(s), if any, in the following program. Also give reason for errors.

int main()

{

const int i = 20;

const int * const ptr = &i;

*ptr++;

int j= 15;

ptr = &j;

return 0;

}
