Question

Answer 1

Because (10 == 20) is false so (a == b) will give 0

so b = a + b + 0 = 10 + 20 + 0 = 30

Answer 2

After putting the values of *a* and *b* which is initially 10 and 20 respectively

The statement :-

b=a+b-(a==b)

Becomes

b = 10 + 20 - (10==20)
As 10==20 is false so will return 0
b = 10 + 20 - 0
b = 30

but the question is why do you think the answer should be 20 ?

Answer 3

How 10 == 20 is 10? Do you know double equal is used for comparing values?

Answer 4

Ok No problem it happens when you learn something new.

Хорошо, нет проблем, это случается, когда узнаешь что-то новое.

Answer 5

I got it. I think 10==20 is 10 and b = 10 + 20 - 10

Answer 9

Maybe you add a as 10, b as 20, and the problem is a + b which pops up 30.
