n+1

none

Question 2

11,11

Question 3

What will be the output of a++ when int a = -1;

1

-1

0 ✓

none

Question 4

If int a = 25, b = 5, c = 0; what value is stored in c? When c = a % b;

5.0

5

0 ✓

none

Question 5

What is the result of the following in Java statement?

Question 6

double c;

int x, y, z;

x = 5; y = 10; z = 11;  

c = x*y+z/2;

The value stored in c is:

55.0 ✓

55.5

55

none

Explanation

   c = x * y + z / 2

⇒ c = 5 * 10 + 11 / 2

⇒ c = 5 * 10 + 5

⇒ c = 50 + 5

⇒ c = 55.0

Question 7

int m, p;

m = 5;

p = 0;

p = m-- + --m;

The output will be:

11

10

8 ✓

12

Explanation

   p = m-- + --m;

⇒ p = 5 + 3

⇒ p = 8
