d. 01
ANSWER: 02
It begins from main I and j globally initialized by 0 and 1. So when we call function i(&x,&y) the address of x and y are passed. When a=b and *a=2 means *b=2, so value of *b is passed 2 and value of *b return to y and value of x and y as 2.
So printf(“%d%d\n”,x,y) give output (0,2)
