Note: ‐ Assume all the required header files are already being included in the code. (2)

‐ The function random(n) generates an integer between 0 and n‐1

void main()

{

clrscr();

randomize();

int PICKER;

PICKER=1+random(3);

char COLOR[][5]={”BLUE”,”PINK”,”GREEN”,”RED”};

for(int I=0;I<=PICKER; I++)

{

for(int J=0; J<=I;J++)
cout<<COLOR[J];

cout<<endl;
}

getch();
}

I) (II) (III) (IV)
PINK BLUE GREEN BLUE
PINKGREEN BLUEPINK GREENRED BLUEPINK
PINKGREENRED BLUEPINKGREEN BLUEPINKGREEN
BLUEPINKGREENRED
Ans. (II) will be the output. Minimum value is 0 and Maximum value is 2 that can be assigned to variable
PICKER.

Q2 (a) What is the difference between the constructor and normal function? (2)

Ans.

Constructor Normal Function
1. Constructor has same name as class name. 1. A normal function can have any legal name
but not class name.
2. Constructor does not have any return type 2. A function can have any return type value.
not even void.
3. Constructor is automatically called. 3. A function is explicitly called.
4. Constructor cannot be static. 4. A Function can be static.
