Comments

@  Bikram sir, according to the answer this is the expression K=1 + j = i, here + is an binary operator which is having more precedence than assignment operator so j must take any garbage value not

Please check sir is it correct ?

BTW this program is not even working it is throwing lvalued error

Because of the bracket the precedence of = inside () is higher than + operator in this case . I hope I cleared the doubt. Correct me if wrong.

Answer 1

Option D) is correct

$k=1+(j=i) $

Since $i=1$, and precedence of $()$ is greater than $+$

$k=1+1=2$
