f) Observe the following program & find out the correct possible outputs from the options.
(Assuming that all required header files are included in the program)
void main( )
{ char serial[ ] = {‘E’ , ‘X’ , ‘A’ , ‘M’} ;
int number[ ] = {69 , 66 , 67 , 68} ;
randomize( );
cout<<number[random(3)] ;
for(int i=0 ; i<4 ; i++)
cout<<serial[sizeof(int) + random(2)-1] ;
}

Q.2 a) Why is a destructor function required in classes ? Illustrate with the help of a example? [2]
b) Answer the questions (i) and (ii) after going through the following class:
class Computer
{ char c_name[20];
char Config[100] ;
public :
Computer(Computer &obj); //function 1
Computer( ) ; //function 2
Computer(char *n , char *C) ; //function 3
};
(i) Name the specific feature of the OOPs shown in the above example.
(ii) Write complete definition for function 1. [2]

c) Define a class named “Housing” in with the following specifications:
Private members:
