A 1 B 2 C 3 D Both 1 and

2

5.Identify which of the following are declarations1 : extern int x;

2 : float square ( float x ) { ... }

3 : double pow(double, double);

A 1 B 2 C 1 and 3 D 3

6.If the binary eauivalent of 5.375 in normalised form is 0100 0000

1010 1100 0000 0000 0000 0000, what will be the output of the

program (on intel machine)?

#include

#include

int main()

{

float a=5.375;

char *p;

int i;

p = (char*)&a;

for(i=0; i


3/22







int main()

{

printf("%f\n", log(36.0));

return 0;

}

A

#include

B

#include

C

#include

D

#include

8.We want to round off x, a float, to an int value, The correct way to do

is

A y = (int)(x + 0.5) B y = int(x + 0.5) C y = (int)x +0.5

D y =(int)((int)x +

0.5)

9.Can you combine the following two statements into one?

char *p;

p = (char*) malloc(100);

A char p =

*malloc(100);

B char *p = (char)

malloc(100);

C char *p =

(char*)malloc(

100);

D char *p =

(char

*)(malloc*)(100);

10.void start() {

A a = new A();

B b = new B();

a.s(b);

b = null; /* Line 5 */

a = null; /* Line 6 */

System.out.println("start completed"); /* Line 7 */

}

When is the B object, created in line 3, eligible for garbage collection?


4/22







A after line 5 B after line 6 C after line 7 D There is no

way to be

absolutely.

11.class Bar { }

class Test

{

Bar doBar()

{

Bar b = new Bar(); /* Line 6 */

return b; /* Line 7 */

}public static void main (String args[])

{

Test t = new Test(); /* Line 11 */

Bar newBar = t.doBar(); /* Line 12 */

System.out.println("newBar");

newBar = new Bar(); /* Line 14 */

System.out.println("finishing"); /* Line 15 */

}}

At what point is the Bar object, created on line 6, eligible for garbage

collection?

A after line 12 B after line 14 C after line 7,

when doBar()

completes

D after line

15, when

main()

completes

12.class Test{

private Demo d;

void start()


5/22







{

d = new Demo();

this.takeDemo(d); /* Line 7 */

} /* Line 8 */

void takeDemo(Demo demo)

{

demo = null;

demo = new Demo();

}

}

When is the Demo object eligible for garbage collection?A After line 7 B After line 8 C After the

start() method

completes

D When the

instance

running this

code

13. public class X

{

public static void main(String [] args)

{X x = new X();

X x2 = m1(x); /* Line 6 */

}

static X m1(X mx)

{mx = new X();

return mx;

}

}

After line 8 runs. how many objects are eligible for garbage collection?

A 0 B 1 C 2 D 3

14.public Object m()

{

Object o = new Float(3.14F);

Object [] oa = new Object[l];

oa[0] = o; /* Line 5 */

o = null; /* Line 6 */

oa[0] = null; /* Line 7 */return o; /* Line 8 */

}

When is the Float object, created in line 3, eligible for garbage

collection?

A just after line 5 B just after line 6 C just after

line 7

D just after

line 8

15.class X2

{

public X2 x;


{

X2 x2 = new X2(); /* Line 6 */

x3.x = x2;x2 = new X2();

x3 = x2; /* Line 11 */

doComplexStuff();

}
