(i) a+=b;
(ii) a%=b;
(iii) a -=b;
(iv) a*-b;​

Answer 1

a%=b, 20

24

I don't know

Answer 2

Answers:

1. a = 36
2. a = 0
3. a = 24
4. -180

Explanation:

1. += operator will add a and b and assign its result to a.
2. % operator returns the remainder, in this statement the remainder will be 0 as 6 completely divides 30, so %= operator will calculate the mod ( get the remainder ) and assign the result to the left operand.
3. -= operator will subtract the left operand with the right operand and assign the result to the left operand
4. a × [-b]
