If unsigned int x = 168 and unsigned int y =60; If z = x & y; What's z?

Question

Please answer this

unsigned int x = 168;
unsigned int y =60;

If z = x & y;

What's z?

Answer 1

It must return 40 to z.
Explanation:
168 -> 10101000
060 -> 00111100
therefore on doing & with each bit we have:
101000 = 40
