Here postfix increment is used. If the statement is "p=++q" then the answer must be 4. But here the right answer is 3.

Here, q is having post increment operator. So, 3 is assigned to p first. Then only q is incremented.

I am afraid, the answer must be option B.

Because when q is declared as 3, here it is also given an operation "p=q++" which shows that there is an increment to be done. So obviously 3 must be incremented form 3 to 4 so the answer must be p=4.

As per to my knowledge assigning is occurs after initialization. But here the p = q++. q is initialized and then assigned to p.

The increment operator is post-fix. So at first the value is of p is 3.

Please explain how could you possible that I think right answer is B.

This is post increment operator, first value assigned and then increment occurs.
