Answer 1

Here is what the program is doing:

(int *p) p is a pointer, it stores the memory address of i

(int *q) q is a pointer, it stores the memory address of j

(p=q) now p stores the same value stored by q: the memory address of j

(*p=2) the memory address pointed by p now stores 2, that means j=2
