Question

Comments

Never encountered such question except 3rd answer all seems to be logical error

---

Can u explain a bit !!

Answer 1

option 1) % has highest precedence then + associative left to right

-13%-5+3 ..( a mod b = a-(b*(a/b))) = $-13-(-5*\frac{13}{5})$ =$-13-(-5*2)$

-3+3

0

2) 3/-3/3 from 1 (-13%-5=-2)

-1/3

-0.3333...

3)  -5%3/13

$\frac{1}{13}$

4) 4/(-10 % -2) /3   $-10-(-2*\frac{-10}{-2})$ =$-10-(-2*5)$

4/0/3 DIVISION BY ZERO ERROR

Comments

small correction :  -5 % 3 is -2 so, it is -2/13

Answer 2

last one..according to precedence % will be calculated first and then divide,so its 4/0 which is a logical error.

Comments

But,the question is asking logical error.And division by zero is a run time error and not a logical error.

@Tesla! can you please give the source of this a mod b formula ? Not understood clearly.
