u.ch[0]=3;
u.ch[1]=2;
printf("%d, %d, %d\n", u.ch[0], u.ch[1], u.i);
return 0;
}
Answer: Option
Explanation:

u.ch[0]=3;
u.ch[1]=2;
Now u.i is calculated as
(2)(3) in binary form which is equal to 515.
(2) --> 00000010; (3) --> 00000011
(2)(3) --> 0000001000000011 --> 515.
u.ch[1]=2;
Now u.i is calculated as
(2)(3) in binary form which is equal to 515.
(2) --> 00000010; (3) --> 00000011
(2)(3) --> 0000001000000011 --> 515.
